A little thread necromancy here, as I've gotten way into board gaming lately with my roommate and her boyfriend. Our current rotation is Settlers of Catan, Carcassone and Dominion, but we're itching to branch out to more complex games. I think Arkham Horror is next on our list, but here's our wish list - anything missing, or any suggestions for games to get sooner rather than later?
Arkham Horror
Agricola
Ticket to Ride
Battlestar Galactica
1830: Railways and Robber Barons
Puerto Rico
Diplomacy
Pandemic
Dominion Expansions
Settlers Expansions
We tend to be up for anything (we're all big nerds, so even D&D type stuff isn't out of the realm), though I'd imagine they would be less likely to enjoy military strategy type games. I'm intrigued by Pandemic, because of the cooperative aspect; the three of us are intensely competitive, and the loser in a heated game of Settlers tends to be a pain to hang around for a few minutes after the game.
