Dale North from Destructoid: It's old-school Sonic, but with a resolution bump. What do you want from me?
I'm kidding. Sega put a bit more work into it than that. Honestly, walking up to my demo station with the game running was pretty exciting. It may sound cheesy, but seeing Sonic 4 in action instantly brought me back to cracking into my Christmas Day Sega Genesis and playing through the first game with my brother in one sitting.
