I love FPSs and TPSs, and play them online all the time.
Right now, I play Halo 2, Halo 3, and Red Faction: Guerrilla the most, but I also play a little Saints Row 2 on the side every now and then.
I'm no pro, but I've heard that I'm pretty damn good, so watch yourself if you step into a game with me.
I also have an immense game collection, mostly because I've gaming since '92 and I refuse to let go of even one game. Most of it is listed in my collection if you want to check it out. GamerNook didn't seem to have the really really old systems listed so I couldn't list my oldest games.
