Fable 5.2 one-shotted my nephew's dream game

A man's nephew asked him to create a custom beat 'em up game for his birthday, and after initially creating a basic version with Fable 5.2, he was able to create a fully functional game with the new version, which includes 5 playable characters, 12 bosses, and a story. The game was created using Fable 5.2, Opus 4.8, and a side-scrolling template from AIOriented.dev.
