Whilst in college:
All Week Long - Assassin
Sunday Afternoon and Evening - Floating RPG
Monday Evening - Battletech
Tuesday Evening - D&D
Wednesday Evening - Rifts
Thursday Evening - Magic
Friday Evening - Vampire
All Day Saturday - Gaming Club
Settlers of Catan, and Magic the Gathering pretty much spackled every other available nook, cranny, or crevice.
[EDIT] Maybe I should go back to college?
[2ND EDIT] It's a shame that we can't do a multi topic poll that plots to a scatter graph. I'd be interested to see how this graph correlates to age.
