Fps,rts

Hi just wondered if anyone can recommend a few good FPS and or RTS games, I have played and completed a few of them and just wondered if there are any out there I should have a look at it. I know this is a bit of a broad question but I am only asking for a few quick suggestions.

Thanks

Very broad, considering you forgot to mention what games you already have, i'll keep it short:

1. Medal of honor: Allied assault
2. Warcraft II: Reign of chaos
3. Command and conquer: Generals
4. Battlefield 1942

I've stuck with Starcraft Broodwar for many years now and still find it better than most.(Granted I can't run many new games) Yet I still find it better than any newer game.
