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, and developer blogs each year, yet most studios making the same mistakes never read them. After collecting and categorizing patterns from a few hundred postmortems across the past five years, the recurring failure modes are striking — and almost entirely preventable.

Scope Cut Late Costs The Most
The most common indie game postmortem regret: “we should have cut scope earlier.” Studios consistently identify the moment they should have removed features (typically 4-12 months before ship) but kept building anyway. The cost: extended development time, exhausted budget, sometimes a worse final game because the cut features had been integrated.
Per Game Developer’s postmortem archive, the studios that ship on schedule almost universally describe aggressive mid-development scope cuts as the reason. Decide what’s truly core, ship that, and treat anything else as DLC or sequel material.
Marketing Started Too Late
Second-most-common indie game postmortem lesson: marketing was treated as a launch-week activity instead of a development-long discipline. Studios that started building audience 12+ months pre-launch consistently outperformed those that started 3 months out — by 5-50x in some cases.
The pattern that works: open Steam page early (even sparse), share dev updates weekly somewhere consistent (Twitter/X, Bluesky, Reddit, dev blog), submit to every free festival, and treat marketing as part of every sprint. For broader launch sequencing, our steam wishlist tactics and game demo strategy posts cover the specific tactics that compound.
Burnout Is The Silent Project Killer
Many indie game postmortem writeups end with “we don’t know if we’d do this again” — not because the game failed commercially but because the team burned out shipping it. Three-year solo crunch projects routinely produce shipped games and broken developers.
Sustainable pace beats heroic crunch over multi-year projects. A useful framing: assume the project will take 1.5-2x your initial estimate. Plan team capacity (and personal capacity) for that timeline. The studios that take care of themselves ship more games over a career than ones that grind.
Engine Choice Rarely Matters As Much As Expected
Indie game postmortem writeups frequently mention engine choice but rarely identify it as a primary success or failure factor. Unity, Unreal, Godot, GameMaker, and custom engines all have shipped successful titles in 2025-2026.
What matters more than engine: matching the engine to your team’s existing strengths, not learning a new engine mid-project, and not switching engines after substantial work. Studios that switched mid-development almost always describe it as a major regret. Game Developer’s developer blogs have multiple examples worth reading.
Playtesting Discovered Problems Earlier Would Have Saved
A consistent pattern in postmortems: “we found this problem in playtesting two months before launch but couldn’t fix it in time.” If playtesting earlier would have surfaced the issue earlier, fixing would have been cheaper. Yet many studios delay external playtesting until late in development.
The cure: get strangers playing builds within 6 months of starting serious work. Builds will be ugly and incomplete — that’s fine. The feedback you get on core mechanics and pacing is irreplaceable, and the cost of changing course is dramatically lower early.
Distribution Beyond Steam Was Worth It
For most indie game postmortem authors, expanding to additional platforms (Xbox, Switch, mobile, GOG, Epic) added meaningful long-tail revenue. The studios that stayed Steam-exclusive often regret leaving 20-50% of potential revenue uncaptured.
The catch: certification, porting, and store-specific marketing all cost time and money. Plan multi-platform from the start if you’re going to do it; retrofitting later is more expensive. For broader monetization framing, our indie game monetization models post covers how distribution interacts with model selection.
Wrap Up
Indie game postmortem reading is the cheapest education available in game development. The patterns repeat across genres, team sizes, and engines: cut scope earlier, market longer, avoid burnout, pick engine carefully then commit, playtest earlier with strangers, plan multi-platform deliberately. Read 10 postmortems before starting your next project. The mistakes you avoid will save more time than reading them costs.
Frequently Asked Questions
Where can I read good indie game postmortems?
Game Developer (formerly Gamasutra) has the largest archive. r/gamedev hosts shorter writeups. Many studios publish detailed postmortems on their own blogs and on Steam community pages a few months post-launch.
Should I write a postmortem after my own game?
Yes, even for solo devs. The act of writing forces structured reflection that improves your next project. Publishing also builds credibility and audience for future work. Aim for 6-12 months post-launch when you have meaningful data.
What’s the most common reason indie games fail commercially?
Insufficient marketing/visibility. Most “failed” indie games are actually fine games that nobody discovered. The second-most-common cause is scope mismatch — game ran out of money or time before reaching shippable quality.
How long should an indie game development cycle be?
1-3 years for most viable indie projects. Sub-1-year projects rarely have enough polish; over-3-year projects usually run into burnout and market timing issues. Plan for the project to take 1.5x your initial estimate.
When should I start telling people about my game?
As soon as you have a stable concept and can show one good GIF. The audience-building runway matters more than the perfection of early shares. Open Steam page 9-12 months pre-launch at minimum.
