Magister Lajciak, the PC version is still very buggy and a patch has yet been released for it. It is a good game, but it is definitely not without its faults, however with games like ME, GTA4, Lost Odyssey (Best JRPG I have ever played), and the like investing in a XBox 360 is very much worth it. And yes, Wrath of Dagon, ME is better than either KotORs by the mere fact alone that it isn't Star Wars.
Well, Bioware did go down hill a little with NWN1 and KotOR1, but have regained momentum with JE and ME.
