Sonic 3... oh wow. Put it with Sonic & Knuckles, and you have something most likely better than Sonic CD. (I haven't played either enough yet.) Awesome levels, amazing music (and innovative too: Angel Island Zone's BGM is in C Mixolydian. Tell me another video game song released before that is in that key), and it's just fun. I first beat the game by itself in Sonic Mega Collection, with all seven Chaos Emeralds. I just got the cart a few days ago (in its plastic case and color-covered manual — pwned, Mega Hit Series owners!). I'll play it later today, and this time I'll win as Sonic and Tails with all seven Chaos Emeralds all got with perfect and all before Launch Base Zone. Fuck yeah.
