age of empires II - this is a VERY old game but i still am addicted to it.
Dungeon Keeper II - Old game again, but high playability.
Deus Ex - Best game ever, havent had chance to play the second; computer not good enough.
the sims - too repetitive and commercialised but good if your bored.
civilization III - the best game there is, if you are bored.
Deer Hunter 2004? May sound like a dumb question, but what do you do? is there any original twist that makes the game exciting. i can imagine it as you having to stand around and wait for a while for game, and when it does come, you miss it, scare it off, and find another place to do the exact same thing...
