Probably the worst thing listening to in a game is another "Master Chief" character open their uninspired mouth. While the Halo character remains one of the flattest, dullest characters ever conceived, I didn't mind it because it was confined to one game. Unfortunately, it seems that every other game that comes out now features a "Master Chief" character with the same psyche (or complete lack thereof) except they possess a different shell. In literature, they call this plagiarism.
