Ground Control II...I don't care much for rts, but i love this game. I dunno if it's what you're looking for, maybe not, but it's an amazing game. It's like Zero Hour on LSD.
Call of Duty (I don't know how the public servers are, I play on a server with a ban list of 1000 people, it's great.)
I think I might know what server that is
Blitzkrieg
Sudden Strike 2
Both are in the WW2 genre, basically you controlling your troops. It does take some planning before you do what you want...and its basically all point and click actions. Can be slow at times but its still intersting and fun, both are cheap too, Sudden Strike, if you can find it, is like 10-15$, and Blitzkrieg can't be more than $20.

I hated the first two but this one is really fun
Warcraft 3 is still good.
Morrowind is on budget now and it sort of goes on forever, very huge game.
Or there's always Roller Coaster Tycoon 2, can be picked up cheap now as RC3 is out soon.
Or Doom III & Half Life 2
Warcraft 3
Call of Duty
