Some really good older PC games?

Can it run Farcry2 or F.E.A.R. ?

Oddworld Inhabitants released a PC port of their FPS game for the xbox... Stranger's Wrath : http://store.steampowered.com/app/15750/ ... although it is kinda of buggy right now...

Chaser: http://store.steampowered.com/app/39670/ another FPS ... takes place in the future but with more realistic weapons. Feels like an old quake type of game total conversion mod.

If you like turn based strategy it's hard to get more classic than the original Master of Magic -- in DOS.

Each turn equates to a month in game. I'm currently playing through it while keeping a monthly Journal as told by a member of the court. I'm also playing it on insane difficulty. I've had to restart several times

Maybe check out G.O.G. dot com for a few real classics? All made to work on newer systems, free of DRM and dirt-cheap.

Masters of Orion 2
Civilization 3(should run smooth if you can handle Half Life)
Alpha Centauri + Alien Crossfire
Command & Conquer's First Decade

Some newer games with lower end requirements that should run if you can handle half life:

Recettear: An Item Shop's Tale (hilarious game, RPG)
Patrician 4(Capitalism sim)
VVVVVV(amazing side-scroller)
Elven Legacy(hex-grid turn-based strategy game)

When you said "older" I was thinking Star Wars Rebellion...but those games mentioned being "older" make me feel a lot "older"
