Have you guys ever been to boardgamegeeks.com? They have a ton of obscure and random board games that aren't your typical MB/Hasbro type games. I've ordered about 5 off that site now. Games like Carcassonne, Wizard, Puerto Rico, etc.
Monopoly and Payday were my favourites..also the one where you rolled a dice and had to reach the middle with like 4 pieces after going around the board once..
