Competitive online multiplayer shooters really haven't grabbed me since back during the days of Unreal Tournament 2004 or the first Call of Duty game. Following those two, I really just lost a lot of interest in the genre. I've been playing it since back in the Goldeneye days (sans the online aspect), and I feel like I've seen pretty much all there is to see in the genre, barring a few innovations here and there such as the leveling system introduced in the first Modern Warfare.

I've always wondered why other types of games get so much flak for failing to innovate, yet first person shooters consistently feature the exact same basic design for their online multiplayer and nothing is mentioned about it. A great example is the rhythm genre, which is falling flat on its face thanks to oversaturation and a total lack of any kind of meaningful innovation. Why do we get sick of those games, but a new FPS for us to play online every three months is a totally welcome release?
