Yeah the fact their ported Xbox games is strange, you would think with Microsoft cash they could at least optimize it.
Didn't know that Steam and Microsoft worked off different ports or code until I ran into this little problem.
Well I hope they see sense and let me play with my Xbox buddies, its no way to treat gamers who pay considering the amount of priacy these days.
Like Gabey himself said, "Its not a pricing problem, its a service problem"
