Game Board Monopoly
Oh, my gosh, my family used to play Monopoly all the time when we were kids. In fact, one of my sisters used to "flip" the board over if she was losing or otherwise not happy -- we can laugh about it now, but boy we used to get so mad at her.
Yes, the original is the best.
There is also a PC game called "Monopoly Tycoon" that is kind of cool to play - similar to the board game except you get to build neighborhood stores and such and see the buildings and the people. We have fun with that, my son and I.
