College Group Board Games

I was recently commissioned to purchase a starting set of board games to make available to our church's college group for use after our weekly meetings.  Our hang-out time afterwards is generally characterized by talking and pancakes (yes, pancakes) and it was thought that the board games might provide some alcohol-free social lubricant.  We did a test run using our own games last Thursday and the response was positive so we got the go-ahead to make it official.

Based on our trial run I was looking for games that had some of the following characteristics:

1. Familiarity to college students/people in general.
2. Easily taught and learned.
3. Relatively short (less than 30 minutes) to play.
4. Good for larger groups (five or more will probably be common).

Not all of the games chosen fit all of these requirements but many come close. And here they are....

I've got a list of further additions if such a need arises but I'd be interested in any suggestions.
