Study: Open-Source Games for AI-Human Co-Op — A Definitive Guide

Kimi research report evaluating 40+ open-source games across seven categories for AI-human cooperative play. 13 pages. Structured assessments with ratings for every viable candidate.

Core Insight

Fundamental tension: Turn-based games ideal for AI's 3-10s decision latency are almost always single-player, while multiplayer games are almost always real-time. No game simultaneously delivers all four priorities: multiplayer co-op + AI-friendly pace + 3D graphics + active community.

Top 5 Final Rankings

Rank Game Viability Why
1 Veloren 4/5 Fully FOSS (GPL v3), native 3D RPG co-op, 22K Discord, WASM plugins. Risk: fast combat challenges AI latency
2 OpenMW + TES3MP 4/5 Best AI-friendly pace (stat-based combat), unmatched RPG depth, server-side Lua. Trade-off: requires $15 Morrowind purchase
3 Luanti (Minetest) 4/5 Most customizable platform, massive mod ecosystem (124+ RPG packages), best Lua API. Trade-off: not an RPG out-of-box, basic graphics
4 Beyond All Reason 3.5/5 Best 3D graphics of any FOSS game, explicit co-op PvE modes, 70K Discord. Trade-off: RTS not RPG, session-based
5 Battle for Wesnoth 3/5 Perfect AI-friendliness (turn-based), genuine co-op campaigns. Trade-off: 2D hex graphics

AI Gaming Frameworks Validated

Three frameworks prove the screenshot→VLM→action architecture works:

  • Serpent.AI — Python, works with any game via screen capture
  • NVIDIA NitroGen — Foundation model trained on 40K+ hours across 1000+ titles
  • BOT-MMORPG-AI — PyTorch, specifically for MMORPGs

Eliminated Candidates (20+)

PlaneShift (closed source UE5), Vintage Story (proprietary), Terasology (dormant), all open-source space sims (single-player only), Flare/FreeDink (single-player), Caves of Qud/ADOM (proprietary), and many others with specific disqualifying factors.

Triage Notes for Timmy

This report validates Morrowind as Rank 2 overall and arguably Rank 1 specifically for Timmy — the stat-based combat and slow pace are uniquely suited to AI latency. Alexander has already purchased Morrowind, making the $15 cost moot.

However, this report also provides a roadmap for the WorldInterface (#871) portability promise:

  • Veloren (Rank 1) could be a future second world via WASM plugins
  • Luanti (Rank 3) has the best Lua API for custom game mechanics — Timmy was already exploring this
  • The architecture is designed so adding new worlds = implementing 3 methods on WorldInterface

Recommended action: Keep Morrowind as primary, but bookmark Veloren and Luanti as future WorldInterface targets. The hybrid approach (Morrowind for depth + Veloren for streaming visuals) is worth exploring once the core TES3MP bridge (#878) is working.

Cross-reference: #871, #878, #896, #867, #886
