I decided to get my Genesis out of the basement to replay Sonic, 2, 3, and Sonic & Knuckles. They still have the same quality and are just as fun as they were when they came out, and it's always nice to hear the familiar music of Green Hill Zone, Icecap Zone, Chemical Plant Zone, and Flying Battery Zone. Even after so much time, even the boss fights against Robotnik retain their challenge (nothing like jumping from hardened lava block to another while the stage slopes and the spikes come from the magma or even the laser dodge in Flying Battery Zone).The games might have passed and returned (Sonic Mega Collection/ Wii points), but in my opinion the crescent shaped controller is the best way to get the feeling of nostalgia and the way it was back then.
