I'm 17 (18 tomorrow, lol) and i have been playing GT since the first one came out, i remember my father telling me about it and he bought it for me, i was totally amazed by the graphics at the time, and i played it alot, beside the fact that i didn't know how to save, so i had to start the game from scratch all the time, lol (i was a little kid).
Sadly i never bought GT2, but i own all the other games, GT is my favourite videogame series since i'm a huge car geek/enthusiast.
