I know its a dumb question but is there a difference between CM 3 and CM 1999/2000?
I heard so much goods about CM so I also want to buy it, but I dunno which one, CM 3 or CM 99/00?
Or are they the same?

help me!!

CM 99/00 is kind of a super patch/update to CM3, and, it is better because it is newer. But do not waste your money now -- but CM 00/01, which also looks like an update to CM 99/00, having a few extra leagues and some new nice features.

Or if you wanna see what your getting, look for a warez site and download it. (CM 99/00 I meen).
