It would take a lot of effort to move the game from Visual Studio 2003 to 2008 or newer. It's not worth doing or setting up at this point.
Well, so much for me volunteering to have a shot at it...
Edit: Wait. Did you think I said that I was willing to try, or that someone at Stardock should do it? I'm not sure if I was clear enough on that point now that I think about it.
Anyways, GalCiv 2 is one of those games that I really liked, a lot. Back in the day when it was still being updated, I would try to thoroughly analyze what ever bugs I found, to try to figure out exactly what went wrong, and try to explain them in simplest terms possible. My reasoning was, the less time you guys had to try to figure out a bug, the more time you guys had to fix bugs and write more code.
I still collect GalCiv 2 bugs from time to time. I'm not sure if you guys still collect them or not (I may have also forgot where to send them), but if you ever want them, they are yours.
