Age of Wonders: Shadow Magic has maaaajor problems with GeForce Nvidia cards, especially the GeForce2 MX versions. If you have that card, Shadow Magic will freak out with the terrain moving about in battle screens and crashing... so far the only solution is to reboot a lot, I heard.
I doubt that, I have also a geforce 2 an MX, and it didnt crash a single time on the hours i have played. It worked fine, no crashes, no strange things happening. Guess i am lucky.:)
