Ever wondered what Minecraft would look like inside Skyrim? Melty offers game mashups that combine elements from games you already own.
One example is SkyCraft, where you explore Skyrim as a Minecraft player. Another is Elden Craft, which brings Minecraft elements into Elden Ring.

Melty is currently free for Windows. Choose a mashup and press Play. According to its website, the app downloads the mod, handles the required setup and starts the game. Multiplayer mashups also provide invite links for friends.

The AI part comes into creating your own mashup. Melty provides instructions for coding agents such as Claude Code or Codex. You describe your idea, and the agent works on building and publishing it.
You still need to own the required games. This looks interesting for players who enjoy experimenting with mods and unusual game combinations.
