Hey Product Hunt! 👋 I built Crownfall because I wanted to see how far AI-assisted development could go. The answer: pretty far. Crownfall is a multiplayer medieval strategy game built almost entirely with Claude Code. It has a full game engine with 288 turns per day, hex-based territory maps, 7 military unit types, kingdom politics with elections and alliances, espionage mechanics, and 4 specialization paths. The game runs in 28-day competitive eras. When a new era starts, everyone begins fresh with equal resources. No pay-to-win, no download needed — just open your browser and play. Era 2 just launched, so this is the perfect time to jump in. I'd love your feedback on both the game and the AI-built angle! 🌐 Play free at crownfall.cz
