I see my sarcasm was utterly lost on you, then. Never mind. Try harder next time.
Linux is a perfectly valid gaming platform. Certainly as valid as Mac OS X. You're going to see more titles for it in the near future, too.
Before you start shouting about games for Window... one of those you mention is X3. Do you have a copy? If so, look me up in the credits. How many times can you find me? (-:
Oh yes, and it's available for Linux.
I agree with you, gaming on linux is vaible and in some cases work better on linux than on windows, valve reported L4D2 better frame rates and better performance on linux than on windows, there is still alot of work to do but slowly but surely games will start to work on Linux Distro more, when the time comes I can finally wipe windows off my machine for good.
