I've played so much of this game. AND, because recently, I stumbled upon the japanese version, as well as N64, I decided to make a little video, where I show all the possible versions you can play.
Kind of. These are not all the versions. There is I believe the PS1 Classics PAL version, and two PlayStation Network versions. But I believe those are hardly different from their original counterparts, so they are not in this video..
Links to the original videos are below, as well as link to the page, where you can view the pictures and covers in HD.
