games in xp

I am not a big gamer but as an experiment i tried to install some games in xp.

I am running suse 10.0 as the host system and windows xp as the guest.

Diablo ll will install fine in xp but when running the video test it tells me the game can't run on this computer.

Tried tomb raiders aod but it will not install at all. Has anyone been able to install, and run games inside a parallels os?
