It wasn't my first game, but I remember when my friend bought the very first Grand Theft Auto, the one with the bird's eye view layout. I remember being so shocked at what you could, and for a while I'd just highjack a car and see how many police I could get chasing me. Even then I remember thinking that the game was going to change the face of gaming forever.
If only someone would have offered me a bet!
