Don't make any special effort on my account but would be curious to know. Always kind of nice I think to see the history/evolution of a game the way
http://www.malfador.com/ has the old Space Empires up as an example. That might be something worth putting up as right now
http://www.bokustrategygames.com/ has nothing. If you ever really got the notion you could probably play Circa 7000 in DOS mode on a Win95/98 virtual machine - I've had some limited success with that in conjunction with
http://www.hpaa.com/moslo/ although I suppose
http://www.dosbox.com/ might be a better solution for games but have not yet tried that.
