That sucks most of the greatest new games are M rated. Anyway I'm going to recommend you an oldie since your taking PS2 games. Beyond Good and Evil, get it, its awesome, get it. Mercenaries 2 for PS3 it T and now its only 40$. Its not game of the year material or anything but its fun. Also I'm gonna recommend a ton of J-RPG's since that's what other's are recommending. Basically any Final Fantasy game is good, at least the main series is. But also you should look for Rouge Galaxy on PS2, its a great game. And I think that rock star game ported a version of Bully to the wii. Bully it closets they could come to a grand theft auto type game with a T rating.
