I agree with almost none of those Draug... Actually I agree with exactly none of those. Where to start...
I have no opinion on some of those categories, but I hate almost all MMORPGs (It's a joke to call them rpgs anyway)
Turn based strategy goes to the Heroes series (Specifically Heroes III) but the Civ series is nowhere near bad, and this was certainly the least offending of your overwhelming display of poor taste. :-P
Strategy - Real Time: Empire Earth. Enough said. If you've never played the game, I'm sorry. It's like Age of Empires (Same developers) except on steroids. It goes all the way from prehistoric to modern.
FPS: Halo? Really? If you want a decent FPS, I'd go with counterstrike. Halo is just... juvenile. It's not realistic at all, and it's really rather basic. Shotgun, pistol, laser, submachinegun, sniper rifle. If you don't place much value on realism, I'd go with Team Fortress 2, which, while also not realistic, is very diverse, and a lot of fun.
