Hey guys i have some great news!
Galactic Civilizations II : Ultimate edition is compatible with windows 8, and it runs more stable and fastr than on windows 7!
i installed galcivii on my pendrive and runned it on a recently installed windows 8 computer and it runned faster and stabler than on windows 7!
I've done this on my hardware course today and it worked!
Just wanted to share this info with the community!
