The original Rayman is a satisfying platformer filled with whimsy & fun levels to explore. It's got a lovely cartoony aesthetic, good control, excellent music & tough but fair challenge. (Eh, for the most part. I feel like requiring all cages for the final world was a bit much.) Crash Bandicoot & Spyro had great 3D platforming on PS1, but for the pure 2D platform fans, OG Rayman definitely has your back.
