Just installed ut goty edition on my lappy, and it runs almost maxed

, doesn't look that bad actually, also a lot of maps I also have in 2k4 ( my 1st ut game was ut 2k4...), overall very nice game but it ate a lot of the lappy's small 12 gb hd'd, any small fps games left that are a must to try?
I suppose in the meantime ill look @ quake 2 and doom 2.
Oh and another request, any good TBS games, already have civ3, but moving is awful due to no numpad, have to click for movement if i want diagonal moves... (and diagonal moves are completly impossible on civ1 & 2)
Already have Space empires 4&5, civ1-3, botf, colonization, but would like some more.
Also copied commander keen 1-6 on it

, and tetris offcourse, and an old footy game called striker.
With rts I have enough I think, got empire earth ( untested yet though), aoe1 + exp, aoe2, c&c ra, installed openttd and stuff, might install pharaoh on it

, rollercoaster tycoon perhaps to revive childhood memory's

?
Hmm also racing games, I have death rally somewhere and carmageddon2, carmageddon 2 seems to dislike me as each time I change settings it crashes, and default controlls are set to numpad, wich my lappy lacks, death rally I need to reinstall/recopy on it and test it.
Any other racing games worth mentioning?
Anyhow in short, any good low space FPS games and good TBS games not mentioned yet?
