From the perspective of a guy who loves multiplayer FPS, I think there's never been a better time to be an FPS fan. FPS games hardly ever die out entirely, and they can be played over the internet with anyone else in the world who happens to like the same FPS game. There's really a game for everyone. There's project reality and America's Army for the realistic FPS fans. For the arena, deathmatch-type games, there's Quake Live, Warsow, CPMA, and Unreal Tournament 3. For team-based games, there's Counterstrike, Team Fortress 2, and Battlefield 3. For people who like old games, you can play Doom 2, Quakeworld, and Quake 2. There are likely hundreds of FPS games that I haven't heard of, and yet have a dedicated following.

You left out the Call of Duty series.
