personally I'm really fond of board games like Caylus, Puerto Rico, the old but still great Full Metal Planete or Funkenschlag. I also enjoy card games such as French Tarot, Poker and Bridge, especially bridge. I started playing it recently but it's really interesting and the random factor is almost reduced to nothing. A beginer can't defeat a confirmed player.
And lastly there is a very fun game I like that has no name I'm aware of. You need two teams. Each player writes down on little pieces of paper anything that crosses his/her mind. When it's done you gather the pieces of paper in a bowl of some sort and then a member of the first team has a definite amount of time, one minute for instance, to make his/her teammates guess the most of what was written down. When the minute is done, the second team does the same thing and you go back and forth between teams until there are no pieces of paper left. It's really fun after a few drinks.
