re: Which board game should I get for Christmas?

We've played Catan with as many as 6...I think that's the max. And it's a game that is very interactive-you have to build a settlement according to how the dice rolls and the board and a big part of the game is making trades with the other players for resources (wood, brick, ore, wheat and sheep). It might sound lame on paper, but once you start playing it is really, really fun.

Not as derogatory as CAH, but it's still fun.
