Indie game postmortem writeups are the most underutilized free education in game development. Hundreds of shipped indie titles publish detailed postmortems on Game Developer, Reddit, itch.io, and personal dev blogs every year, yet most studios making the exact same mistakes never read them.

After collecting and categorizing patterns from postmortems published over the past several years, the recurring failure modes are strikingly consistent — and almost entirely preventable. Below are the seven lessons that show up again and again, where to actually find good postmortems to read, what separates the indie developers who succeed from the ones who don’t, a realistic development-timeline check, and a simple template for writing your own.
Quick Answer
The lessons that repeat across nearly every indie game postmortem: cut scope earlier than feels comfortable, start marketing a year or more before launch, protect the team from burnout by assuming the project will take longer than planned, pick an engine that matches your existing skills and stick with it, get strangers playtesting within the first half of development, and treat distribution beyond Steam as real revenue rather than an afterthought. The indie developers who succeed commercially tend to share one trait above the rest: they finish something smaller than they originally imagined, on a timeline they padded instead of optimized.
Where To Actually Read Indie Game Postmortems
Game Developer (formerly Gamasutra) runs the longest-standing postmortem archive in the industry, with writeups covering everything from budget and team size to marketing spend and post-launch sales. itch.io has a dedicated postmortems tag under its devlogs section, where solo and small-team developers post far more candid, unfiltered breakdowns than a polished press piece usually allows.
Reddit’s r/gamedev and r/IndieDev regularly feature developer-written retrospectives, often with real revenue numbers attached, and GDC Vault hosts recorded postmortem talks — Adam Robinson-Yu’s “Crafting a Tiny Open World,” about the making of A Short Hike, is one of the most frequently cited solo-dev examples. Reading five or six recent postmortems in your own genre before starting a project will teach you more about realistic scope than any planning template.
Scope Cut Late Costs The Most
The single most common indie game postmortem regret is some version of “we should have cut scope earlier.” Studios can almost always pinpoint the moment they should have removed a feature, but kept building anyway because the sunk cost felt too large to walk away from. The result is extended development time, an exhausted budget, and sometimes a worse final game because the cut features had already been half-integrated into everything else.
Postmortems that describe an on-schedule launch almost universally credit an aggressive mid-development scope cut as the reason it happened. The practical fix: decide what’s truly core to the experience, ship that, and treat everything else as a candidate for a post-launch update, DLC, or the next project entirely.
Marketing Started Too Late
The second most common lesson: marketing was treated as a launch-week activity instead of a development-long discipline. Postmortems that describe starting audience-building a year or more before launch consistently describe outperforming comparable games where marketing began only a few months out.
The pattern that works across writeups: open the Steam page early even if it’s sparse, post development updates on a consistent cadence somewhere the same audience can find them, submit to every relevant free festival and showcase, and treat marketing as a recurring task inside every development sprint rather than a separate phase tacked on at the end.
Burnout Is The Silent Project Killer
Many indie game postmortem writeups end with some version of “we don’t know if we’d do this again” — not because the game failed commercially, but because the team burned out shipping it. Long solo or small-team crunch stretches routinely produce a shipped game and a developer who needs a year off before touching another project.
A useful framing that shows up repeatedly in postmortems: assume the project will take meaningfully longer than your first estimate, and plan both team and personal capacity around that longer timeline rather than the optimistic one. Developers who protect their own pace tend to ship more games over a career than the ones who grind through one and disappear.
Engine Choice Rarely Matters As Much As Expected
Indie game postmortems mention engine choice constantly but rarely name it as the primary reason a project succeeded or failed. Unity, Unreal, Godot, GameMaker, and fully custom engines have all shipped successful and unsuccessful titles. What matters more, according to the writeups themselves: matching the engine to your team’s existing strengths, not learning a new engine in the middle of a project, and not switching engines after substantial work is already built.
Studios that switched mid-development describe it as one of their biggest regrets in almost every case — the migration cost consistently outweighs whatever the new engine promised to fix. Game Developer’s postmortem archive has several concrete examples worth reading firsthand, including the A Short Hike postmortem, which covers a solo developer reusing tools from a previous project and leaning on lightweight solutions like the Yarn Spinner dialogue system instead of chasing a new pipeline.
Playtesting Earlier Would Have Saved The Launch
A recurring pattern across postmortems: “we found this problem in playtesting two months before launch but couldn’t fix it in time.” The problem itself wasn’t unsolvable — it was discovered too late to solve cheaply. Yet many studios still delay external playtesting until late in development, often out of a reluctance to show unfinished work to strangers.
The fix that postmortems describe working: get strangers playing builds early in serious development, while the game is still ugly and incomplete. That’s fine — the feedback on core mechanics and pacing is irreplaceable, and the cost of changing course drops dramatically the earlier a problem surfaces.
Distribution Beyond Steam Was Worth It
Postmortems that track revenue platform-by-platform commonly report that itch.io, the Epic Games Store, GOG, and console ports — Nintendo Switch in particular — add meaningful revenue once the initial Steam wishlist and launch-week curve flattens out. The lesson isn’t to launch everywhere on day one; it’s to plan the rollout deliberately.
The pattern that recurs: launch on Steam first to build reviews, visibility, and wishlist momentum, then stagger additional platforms and a console port over the following months rather than treating them as an afterthought once Steam sales have already cooled.
How Indie Developers Actually Succeed
Postmortems from commercially successful indie titles point to a consistent handful of habits rather than any single breakthrough. Every visible part of the game — art, sound, UI, marketing copy — is polished even when the scope is small, because players judge a small game on craft, not ambition. Successful teams also tend to pick a specific niche audience deliberately rather than trying to appeal broadly, since a smaller, well-served audience out-converts a larger, indifferent one.
The rest of the pattern: build community and a mailing list or Discord before launch instead of after, treat the game as one of several revenue streams (bundles, merchandise, publisher deals, later ports) instead of a single make-or-break bet, and carry enough personal runway — savings, a day job, or grant funding — to survive a slower-than-expected sales curve without panicking into a rushed launch.
Why Indie Games Actually Fail Commercially
The most common failure described across postmortems isn’t a bad game — it’s an invisible one. A well-made, well-reviewed title with no audience built ahead of launch routinely undersells a rougher game that spent a year building community. Steam’s catalog is large enough that discoverability, not quality, is the more common bottleneck.
The other repeat causes: running out of money or time before reaching a sustainable audience, scope creep that delays launch past the point the team can financially sustain, and burnout-driven launches that ship before the game — or the marketing plan — is actually ready.
How Long Should Indie Game Development Actually Take?
There’s no reliable single average across postmortems — timelines vary enormously by scope. Game jam projects ship in days; small commercial titles built by a one- to three-person team commonly run one to three years; ambitious solo passion projects have documented cases stretching much longer. Stardew Valley was originally planned as a roughly six-month project and instead took about four and a half years of solo development. Animal Well took roughly seven years, also largely solo.
A Short Hike is the useful counterexample: a small, deliberately scoped solo project built in a few months after its developer set aside a larger, more ambitious game. The lesson that repeats across nearly every postmortem: whatever your first estimate is, budget meaningfully more time than that, and let scope — not the calendar — be the thing you cut when the two conflict.
How To Write Your Own Postmortem (A Simple Template)
A useful postmortem doesn’t need to be long, but it does need to be specific. Cover five things: what the game was, including team size, budget, and timeline; three to five things that went right, named concretely rather than generically; three to five things that went wrong, including the exact decision or date where it went sideways; what you’d do differently starting tomorrow; and, if you’re comfortable, real sales or wishlist numbers.
The postmortems developers actually learn from are the ones that name specifics — “we cut the crafting system in month eight” instead of “scope was an issue.” Publishing it on itch.io, a personal dev blog, or Game Developer adds it to the same pool of writeups this article draws from, and it costs nothing but honesty.
indie game postmortem lessons FAQs
Where can I read good indie game postmortems?
Game Developer’s postmortem archive, itch.io’s dedicated postmortems tag under devlogs, r/gamedev and r/IndieDev on Reddit, and recorded GDC talks on GDC Vault are the most consistent sources of detailed, developer-written postmortems.
What do successful indie developers do differently?
They polish every visible part of a smaller game rather than half-finishing an ambitious one, target a specific niche audience, build community before launch, plan multiple revenue streams instead of one big bet, and keep enough personal runway to avoid a rushed, panic-driven launch.
Should I write a postmortem after my own game?
Yes — even a short one. Naming exactly what went right and wrong, with specific decisions and dates, is more useful to your next project (and to other developers) than a general impression of how development went.
What’s the most common reason indie games fail commercially?
Invisibility, not quality. Postmortems repeatedly describe well-reviewed games that undersold because marketing and community-building started too late, not because the game itself was bad.
How long should an indie game development cycle be?
It depends entirely on scope — jam games take days, small commercial titles commonly take one to three years for a small team, and ambitious solo projects have documented cases running four to seven years. Budget more time than your first estimate regardless of scale.
When should I start telling people about my game?
As early as you have something worth showing, ideally a year or more before launch. Postmortems consistently show games that opened their Steam page and started posting updates early outperforming comparable games where marketing began only a few months out.
Is it ever okay to switch game engines mid-project?
Postmortems almost universally describe mid-project engine switches as one of their biggest regrets — the migration cost tends to outweigh whatever problem the new engine was meant to fix. It’s far safer to pick an engine that matches your team’s existing skills before starting.
