Just a thought about game replayability. I got Master of Magic shortly after it was released. Up until I installed Win XP it was on every machine that I owned starting with my 486 DX 50. Recently I was able to get it to run on XP with a combination of DOSbox and D-Fend. So lately I've been playing it yet again. This is even after I just got a Geforce 6800 CS/OC 256MB vid card.
The graphics are, shall we say, less than state of the art.

But that game is probably my favorite strategy game of all times.
From what I've read about GalCiv2 it has all of the things that could make it another classic strategy game. Anybody else have a really old game that they still play, or would (if they could get it to run)?
