I would have been drawn to Crash. Do people remember what it was like to play games then? Do you remember how blown away you were the first time you saw a game in 3D? In 1990 there was literally nothing else like that. Rayman is definitely the more impressive game now, but back then I still understood that style of gameplay.
Of course, if you put them side to side with Crash playing on a 24" CRT and Rayman on a 60"+ flat screen, that makes the question a lot more complicated.
I was wondering why I kept losing my connection to the server today, and finally came in to read the thread. It took me forever, but I got around to making my community page; could I be added to the steam group?
