I wanted to know if anyone has had any further success with GalCiv2 on Linux.
My switch to Linux shortly after I got the original GalCiv2 is what has kept me from buying the expansion pack. If GalCiv2 Dread Lords and Dark Avatar work properly on Linux (via Wine or Cedega), then I'd go and get the expansion

I did try GalCiv2 in Wine (or Cedega, I forget) a few weeks ago. It didn't go so well. I have an LCD monitor, and I think the minimum resolution is 1024x768 (the recommended is 1280x1024, which is what I'm running at). But when I started GalCiv2, it ran at its minimum resolution, which meant it wouldn't display on my monitor. Though, the game crashed after the opening FMV, anyway. I figured out how to run it in Windowed mode, and whether I skipped the FMV, or it ran to the end, the game crashed afterward.
In the other method (Wine or Cedega, whichever the previous attempt was not), I couldn't get the game registered. It gives me an error about something not matching. It's annoying. I understand Stardock's position, but at the same time, I bought the game and I can't play it without rebooting my computer. And I don't know any other method to play it.
