I used to play a game called Auto Destruct a lot, which was rated M, but all fun games had a high mature rate, right? Anywho, it was pretty fun; it's like the game Twisted Metal, except you go on these missions to destory these bad guys who threaten the world, etc. It was very desructive, and had a variety of weapons for your car!
Another game that I loved was Crash Bandicoot: Warped and Crash Bandicoot Racing. The Crash bandicoot games in general were pretty fun; though I found myself playing Crash Bandicoot Warped a lot. Crash Bandicoot Racing was really fun too, although, I used to suck at Racing games and it got me a real long time to get used to everything, buuuuut, all in all, fun racing game! I'd say try it if you have the opportunity to play it!
Ah yes, and the Spyro games - I forgot the titles, but I played the one with Ripto, Gulp, Crush, etc. those bad guys, and Year of the Dragon, which was great, but, god I used to think it was a tough game.. Ah, how wrong I was years later; I find it pretty easy now, but still fun nonetheless!
