You're propably right. Few days ago I've bought myself a 486DX2/50Mhz laptop. I don't believe, that I'll be able to do anything on it, apart from old games. I'm figuring out whick games will work, by the year of publishing. GTA, Syndicate wars, Ignition - these games, I'm pretty sure won't work.
But about the requirement I thinked about one more thing. Wouldn't it be some history lesson to get to know, what machines were enough to play some time ago? Someone could look at the games from crypt, find out that only 286 was neccesary to play, and smile

k:
Isn't that kind of interesting just as a historical info? Are there any pages on the web, that provides this information? If not, why don't we be the first?
