Feature: I want to be able to import custom 3D models so instead of playing as Kwan, I can play as Cloud from Final Fantasy, the Princess from Frozen instead of Aurora, The Hulk Instead of Steel, etc.
Context: I've done it in other games (Fifa/FC & NBA2K, see pictures) and it's probably the most fun I've had playing a game, ever. These mods only affect what YOU can see, other players online will see their own local files or mods.
Suggestion: Provide a folder for PC players where they can place mod files and have the game read those files instead of default textures and 3D meshes. For console players, add file sharing system to download mods.
