Well in the simplest terms, a game engine controls the physics, graphics, and performance of a game, with that being said, its a foundation that the game builds upon. and knowing which engine is used just helps us (the fans) breakdown the game further.
What engine does this game use? From what I've heard it either uses a modified and improved KH:BBS Engine or a modified KH2 Engine, anyone got a straight answer?
Besides boobs, I hope there's a Princess and the Frog world (Facilier vodoo-heartless FTW), and a world based off Tangled, and maybe Atlantis:TLE while thy're at it.
