I just got Sins of a Solar Empire & it seems to crash my system after like 15 min of play... I havn't check on XP yet, but I plan to this weekend when I have time. But it's kind of annoying that it's been crashing my system from playing. My other games don't have any issue whats so ever, I mostly play WoW and I can stay logged into WoW for hours /w no problems what so ever.
