Someone donated a PS 1 to my son, and now I'm going to try and find him some games. Frankly, I was never into PS1, and I'm a little overwhelmed! Which are the absolute best games for kids? He's pretty good at Mario type side scrolling games. I would also be interested in multiplayer "Mario Party" type games that kids can play, or cooperative "Lost Vikings" games? Or racing games geared for kids (no pun intended). Thanks.
