A 10-year game dev, a year into AI-assisted development, posts a reality check: 8+ months into an AI-coded farming sim he has no playable demo and barely any screenshots — but has finished a huge amount of infrastructure underneath. The thread (140 points, 50+ comments) settles on a shared pattern: generation is the fast part, deciding is the slow part.

  • “Oneshotting with AI just means you’re getting AI slop. Game dev is about decisions, art direction and design, and the AI is definitely useful, but it doesn’t replace your vision”
  • “The fastest part is often generating something. The slow part is deciding if it actually belongs in the game, testing it, breaking it, rebuilding it” — an 18-month solo dev
  • Iteration is the real bottleneck: one system through 5 redesigns, a UI screen through ~10 before it was “decent enough”; brainstorming with AI yields “12 ideas to reject and 1 idea that’s kind of shaped right”
  • The invisible work dominates: NPC pathfinding, schedules, dialogue, animation (“AI cannot make my animations”); pure code systems are a minute, anything needing visual input is not
  • “The AI is a code machinegun. It is not a UI/UX guru. It is not a balance guru. It is not a modularity guru”
  • Infrastructure-first development — databases, admin tools, refactors — is “the hard and invisible part,” not flashy enough for Twitter but essential; “don’t create games, create systems”
  • The counterpoint got voiced too: industry makes a playable prototype first thing even without AI, so eight months without one reads as a red flag (“smells like cope”)
  • “AI slop” has collapsed into “I think this looks like low effort” — the same accusation that used to be shovelware or asset flip, now aimed even at pre-AI games

The useful mental model: AI compresses implementation, not judgment. The constraint that used to be “writing the code takes forever” has moved to “deciding what to build and making it coherent takes forever” — which is exactly where the human work lives.

For anyone judging progress in the AI era, demos lie and infrastructure doesn’t. A great-looking “vibe coded in a week” clip is a vertical slice, not a game.
