Here's some more I'd like:
* A turn-based strategy war game like Steel Panthers.
* A 4X game like Civ or Galciv
* RPGs, could be like the old Fallout or Ultima. I played Dungeon Hunter, but it was too simplified and short.
* A good trivia game, like 1v100 or even Trivial Pursuit. Both SP and MP.
* Board games like Taboo.
