not sure if the gran turismo games have actually changed my life but they've always been around.
i bought gt1 a week after it first came out here, and have bought every other gt within a day or two of there release. i dont play the pre gt4 games much anymore, but i still have them all just in case i feel the need. they have taught me a bit about settings and tuning cars as well as driving, eg racing lines etc... sometimes i get bored with racing and might go 2 or three weeks without playing it, i usually replace them with one of the MGS's or GTA's wich i have collected alongside GT's throughout the years, but i always come back to it when i get bored with them.
not sure what year it was now, but i was in year 7 or 8 at school when GT1 came out, i remember playing it with one of my mates (we still have massive 2 player battles with GT4 and TT) untill my thumbs were blistered and bleeding (nothing to do with the brian adams song

) but they grew tougher and were fine by the time GT2 came out.
