Hubby and I have been playing Elder Sign with some friends. I love the art work on the cards, it really seems to capture the mood of Lovecraft stories. It is basically a co-operative dice game, but it is fun. It also has the added bonus of being able to finish a game in a decent amount of time (the last time we played Arkham Horror it took 6 hours, and we were nowhere near finishing the game!).
Arkham Horrors is insane. A little to much so, even though it's a good fun.
