Galactic Civilizations-Had if for awhile, but never played it, now, I can't seem to get off!
Operation Flashpoint-Heard it was good, saw the preview for it, fell in love. Still love to play it after about year of beating it, The expansion packs are cool too.
Fallout 1, 2, and Tactics of course. Although lately, I haven't been playing it much, or at all.
Stronghold-Reinstalled it yesterday, made my own map, made it look like the castle in Lord of the Rings 2. It's awesome when you have 500 knights, swordsmen, archers, and trebuchets charging at you.
Delta Force 2-I just get a kick out of terrorists screaming for their mothers!
C&C Generals-Iraq, killing terrorists, tanks, need I say more?
And finally, if I ever get some extra time, Medal of Honor games.
The only problem with trying to sit there on my sorry ass playing games all the time is that I still have school to go to, school sports, and I got to work if I want to be able to drive (gas, car bills, etc...), buy more games, and party every once-in-a-while.
