PS2 games

One thing that I noticed today while at the game store was the PS2 games. They are $10 and lower. I really wish that our new PS3 was backward compatible (could play ps2 games on it) but it is not:/ Most of the games that we have for our new console are for our little boys. They do not care if the games are the best new thing or if they have been out for a few years. They do love their Lego Batman, Indiana Jones and Star wars games though...Now just trying to get the Lego version of Rock Band;)
