Why don't I "get" disney infinity 2.0???
So, each character or figure comes with certain levels you can play with them. Think of these as traditional video games.
The Toy Box exists separately from these games. It's an open world that you can build, sort of like minecraft, but with preset set pieces. Like race tracks, castles, trees, flowers, etc. You build the land, the terrain and whatever you want. It all snaps together. For this game mode, the character you are using doesn't really matter, except that you are using that character.
