Sonic Chaos (or Sonic & Tails) is a laughably easy game, but generally fine enough. Short enough to get through in a half hour it's somewhat forgettable but innocent and charming enough. Going for all emeralds as Sonic sees every stage turned into a treasure hunt for rings, regurgitating some of those Sonic CD problems, split up by whacky little special stage trials which makes the game feel more like a minigame collection than a platformer. The game, much like it's soundtrack, is inoffensive but forgetable.
