Here's why:
* Disney Infinity is a toy-to-life game. This means you use physical figures (the characters) to unlock their digital counterparts in the game.
* Each character has unique abilities and gameplay. Different characters offer different playstyles and approaches to the game's challenges.
* The figures are essential for playing the game's levels and stories. Without the figures, you won't be able to access the content they unlock.
So, while you don't *have to* own any Disney Infinity figures, you definitely need them to enjoy the game's full experience.
