You can't go back again

Playing on the 360, I decided to play some classic games like Frogger, Sonic, and etc. It made me wonder what did I like about them in the first place. I guess now I am just a different gamer, or the thing I really liked about them then was that it was a just a completely new experience. Maybe it is a little of both, I just don't like those games anymore.

Classic games, like? Dislike?
