Farcry, Gothic 2, system shock 2 with some friends, Baldur's gate 2 (for the 6,000 time) and Allegiance.
Gothic 2 is pretty good, takes skill to fight well amazingly enough.
If you like space combat games, I'd suggest Allegiance. It's a game Microsoft released long ago and is now free (they released the source code for it).
Basiclly, it's multiplayer team based space combat, with one person commanding the team. The commander builds structures and researches technology and new ships/weapons for the team. It takes a lot of teamwork and is incredibly cool with stealth elements, sneak attacks, massive capital ships with 6 or so turrets. Another interesting thing is it has many voice 'emotes' that really add to the whole atmosphere of the game.
