worried - PC and Xbox games suffer (Score 3, Interesting)

Really liked Thief 1 and 2 and DeusEx. I heard all these good things about the Xbox Halo, tried it for the first time on PC and it was mediocre at best. Poor graphics and poor frame rate. The same textures over and over again, the same rooms over and over again. I am not hearing good things about DeusExIW ... but I have not tried it yet. XBox+PC games seem to inherit the problems of each platform and lack any benefits one could releaize if the game was developed for a single platform. Just some thoughts ... I really hope Thief III is a great game but I will likely wait for the reviews.
