There was a Sonic thread a while back, but this is a Sonic 2 specific one. What's your favourite zone, and least favourite zone in Sonic 2? And why?
My favourite zone is Casino Zone because it has those things you can land in and try to get the jackpot. I used to spend so much time jumping in those I'd run out of time on the level xD It's fun bouncing off of everything too.
My least favourite is probably Aquatic Ruins Zone, I hate any zones with water in, too much pressure to get air, scary.
