The PC/PS2 version is a pretty simple collectathon level based 3D platformer that can be completed in a few hours. Nothing ground breaking and it is a PS2 game of its era, so expect some jank from strange collision detection, awkward jumping physics, and somewhat blocky textures, but it gets the job done and it still manages to retain a good amount of charm from the movie. I have played the PS3 version of WALL-E and that plays like a much more expanded game with even more collectables and more complex puzzle mechanics (and you get to play and fly around as EVE more) but haven't finished it, so I might update my review in the future if I end up finishing that someday.
