Sonic Classic Collection - Knuckles in Sonic 3 Gameplay
Here is some gameplay from the new Sonic compilation: Sonic Classic Collection for the Nintendo DS. This compilation is an on-the-go collection of the three first Sonic games along with Sonic & Knuckles and versions of the first games where Knuckles is playable. Here, I play some Sonic 3 with Knuckles. Now, I could easily play Sonic & Knuckles if I wanted to, but "Knuckles in Sonic 3" makes it so you play Sonic's story as Knuckles. I dunno, I find it interesting.
So anyways, this is basically just another Sonic compilation. No upgraded graphics or anything, though there is some sort of new save function where you can save any time you want. It's a good collection if you want to play Sonic games anywhere you go, but other than that, it's kind of pointless, considering there are other and better Sonic compilations.
