Halo 2 may be the most hyped game ever, but it is not the most overrated game ever because it has an incredibly addictive and fun online component. True, it can get boring to play the same CTF match for the hundreth time, but custom games give you the variety to keep things fresh. The story in the first game was a bit bland, but they really pumped it up for the sequel. If you consider the story to be unoriginal, you obviously didn't play much of the game or simply didn't pay attention, because it has quite a few unusual twists. While Halo has never done anything revolutionary, Bungie managed to take great aspects from various shooters and incorporate them all very well.
