WoW, mw2 was good when playing it with my brother, but everything they did to the pc versions online play made it really drop in appeal for me.
I agree with everyone that said American Idol.... Infact I hate just about every reality TV show there is... Even Mock-reality tv shows are poorly done..
Halo... Sure the first one was alright to play through, but I don't think it deserved to become a trilogy, let alone have it's own sequel. From what I've seen of online play between the three of them.. Not much really stands out as different.. Besides the ability to play as the alien, but no one ever does. Online play just looks too generic... There's no strategy involved... That I could see anyway. Atleast in other fps games... You can tell that the players minds are constantly working.
Even playing the first halo online... I didn't feel like I had to put much thought into what I was doing, that was a major set back for me..
