My pen and paper RPG group has taken a bit of a break from D&D lately to play more board games and I've actually really found myself liking what we've played, even if the setup time can bit a bit ridiculous (looking at you Arkham Horror).
Last time we met up we played a game called Tomb, which was pretty fun because each player got a chance to be a DM for a brief moment. It went by really fast, with three players we got a full game in less than 2 1/2 hours.
Other games we've played that I would highly recommend:
Munchkin + any expansion
Munchkin Quest. A little hard to set up, but a good change of pace if you're a massive munchkin fan
.
Talisman. Now granted I've only ever played an older edition, but this is all the fun of D&D without any of the work.
RISK 2122. Do you like RISK? Do you also like going to bed at an appropriate hour and not having to disown three friends in the process? This is a great take on the game because it's cut down to 5 turns each player, and you win by how many points you have, which can be earned multiple ways.
RoboRally. This is another one of those older games, but man it's a lot of fun and is pretty strategic too. Can be a little frustrating if you program your moves wrong, but still a solid game.
Illuminati. This one is pure strategy, but it can be a little confusing.
Arkham Horror. Takes forever to setup, but if you're a fan of Lovecraft then this game is definitely worth your time.
Those are all the big games we have played lately, all of them fun.
