+1 for King of Tokyo, it's super frantic and loads of fun whilst still having a minor tactical element.
Another recommendation for King Of Tokyo, I'll also add a huge recommendation for this years KennerSpiel Des Jahres winner, Isle Of Skye, a 4 player game is around an hour, a little quicker once you've played it once or twice, though it does depend on the group you play with... AP can be a big factor...
