I am sorry but this game blows! Its very sucky and there are barely any family games(4 player i mean)!!! It needs to be taken off the market. Complete with anoying elivator music, only 3 four player games. Chineese Checkers, connect 4, and battle ship. I would strongly advise you to throw the game away if you already rented it!!!!
I think I figured out the 20 game vs. 12 game issue. The PS2 version that came out in 2006 had 20 games on it including some of the ones people were complaining about not having like Go, Mancala and Concentration.
Some of the controls are kind of bad, I kept dropping things in the wrong places too. But it is something different to play that is simple and easy paced.
