Time to show my age now, I got GT on its release date in the UK. I can clearly remember first reading about it in the mags before release and seeing the first video clips. Like a total sad git, I used to watch the intro video (which was on an OPSM demo disc) almost every day in the weeks leading up to release.
At the time the PS had nothing like it, a true driving game for road cars, with so many tracks and cars, heaven for a total petrolhead like me.
Since then I have been luck enough to get every game in the GT series on its day on release (including GT:C, GT4 Prologue and the BMW demo), the first one got me hooked and over 7 years later here I am.
