The wife bought me Arcadia Quest for my birthday. So far, it is a blast. A 6-scenario campaign game, where all players control a small guild of three Heroes trying to free the city of Arcadia from the domination of Lord Fang- with each guild attempting to reign supreme (and remove the competition when possible). A great deal of fun, but if your group prefers cooperative games, this is definitely not that!
In addition, I also just recently picked up Keep Talking and Nobody Explodes on Steam. I include that because it is a fantastic party game- place a laptop at one end of the table, where the bomb defuser sits, and give all other players a printed copy of the bomb defusal manual (located at bombmanual.com) and have them sit at the other end of the table. The bomb defuser has to describe what he sees, and the disposal ‘experts’ guide him to defusing the bomb by looking through the manual… hopefully. For extra fun, you can separate the groups even more (different rooms and shouting, speaking through a cell phone on speaker, on skype, etc.) Just a great time, and now part of our board game night rotation.
