One of the best Sonic games of all time (even though I like Sonic Battle and SADX more). PC version is almost not enjoyable without mods. Great music and art direction, but kind of outdated level design. Story is also quite good, especially for a Sonic game (Sonic Battle still has better story). The best thing in this game is Chao Garden, where you can take care of adorable little creatures called Chao. They can grow into different types, depending on how you raised them. SA2B has the most complete Chao Garden experience. This is the reason to play this game.
