Since someone mentioned character battles, I have to laugh when it comes to the Knuckles battle. You really do just homing attack the man 3 times and he's done, there's hardly any pomp and circumstance to it. It's so uninteractive that I hardly consider it part of the game anymore, like the Knuckles fight from Sonic 3 (although he actually kind of puts up a fight in that one). It makes me wonder how that kind of character battle would be received today. I can imagine reviewers being like "...that's it?"
