I was thinking about getting a PS2 also as there are some games that never made it over to the PS3, like SSX Tricky. They've stopped allowing the PS3 to play PS2 games in the latest rounds of the firmware upgrades. Hopefully, they will bring that option back again. The Wii looks like it might be fun for some of the games that have been coming out for it.
Kids seem to pick it up pretty fast from the younger ages. It's fun to watch them, isn't it?
