This game was hard as balls. As a platformers fan, when I bought my PS1, I paused in front of the store shelf for long minutes, choosing between Rayman and Resident Evil.
In the end, I chose RE. One of the best decisions of my life. I tried Rayman later and boy, what were they thinking?
It's cool that they included several versions, but seriously, who is going to play the GBA version? Jaguar at least has some historical merits, and I understand that it has some differences worth going through it.
The rewind feature and the cheats are surely a welcome bonus. I rarely give up on this kind of game, but Rayman really broke me back in the day.
