What's new (2026 refresh)

• Reviewed the upstream PR backlog: merged 11 useful contributions with their original authors credited in the git history, and declined spam, off-topic tools and dead links.
• Added new categories: 3D Model Generation, 2D Sprites & Pixel Art, World & Level Generation, Engine Integrations & MCP Servers, Music & Sound Effects, Playtesting & QA, and Showcases & Galleries.
• Added 2025–2026 tools, including Hunyuan3D 2.1, TRELLIS.2, Meshy, Tripo, PixelLab, Retro Diffusion, Unity AI, Bezi, Blender/Unity/Godot/Unreal MCP servers, Chatterbox, Kokoro, ACE-Step, NobodyWho, LLMUnity and nunu.ai.
• Fixed dead links and removed tools that have shut down, been abandoned or been superseded.
• The numbers (counted from this file): the list has 94 unique tools in 98 entries; Ludo.ai, Rosebud AI, Stable Diffusion 3.5 and ChatGPT each appear in two sections. The original list had 35 tools. 18 of them are still listed (Stable Diffusion is now Stable Diffusion 3.5, Claude 100k is now Claude, and GPT-4 32k is now OpenAI API models). 76 tools are new, and 17 of the original tools were removed.
• Removed from the original list (17):
  • Shut down: Ready Player Me, Luma Genie, Charmed Texture Generator, Charmed Tilemap Generator, RADiCAL, Coqui Studio and Replica Studios.
  • Abandoned (no updates since 2023–2024): Haddock, Plask, eastworld and UnityMLPySocket.
  • Archived: Hugging Face API Unity Integration.
  • Outdated models with better replacements: MPT-7B-StoryWriter, StarCoder, ControlNet v1.1, Facebook Wav2Vec2 and Bark.
• Added during the refresh and later removed (4): Stable Fast 3D (no updates since January 2025; TRELLIS.2 and Hunyuan3D 2.1 do the job better), chongdashu unreal-mcp (no updates since April 2025; the actively maintained Unreal-MCP is listed instead), Udio (downloads and commercial use ended after the October 2025 UMG settlement) and Aicade (no sign of activity since 2024).
