Why?...well, I'm afraid there isn't enough words that can describe why. And I say this being perfectly aware that there's thousand of verbs and adjectives in the English language that could come pretty close.
After beating the beans out of GT2, my next sept would be GT3. I got a brand new PS3 Christmas 2001, and along with it came GT3. I was already a sucker for the Gran Turismo name, and I was in for one hell of a ride...
Back then all my school "friends" had the bad habit of never returning borrowed items, and due to my naiveness I lost the GT3 disc for the first time. I was heart broken, because for the first time I found a way of expressing the love I had for cars. Nothing came as close as GT3 in saying how much I loved cars. And for a 11 year old boy, who spends most of his time alone, GT3 was the only true friend that I had.
At the age of 14 I was forced to move to the big city along with my parents due to serious financial problems. After things picked up a bit, my parents were able to afford buying me a new GT3 disc, and I was over the moon...until I feel for the same trick again.
And then, one day, at the age of 16, I got myself some pocket money. GT3 was history by now, all the heat was on the upcoming GT4 instead. But I still wanted GT3. I walked all over town, store after store looking for GT3, but I couldn't find it...until, at 10pm in the evening (nearly 6 hours later after I started my quest) I finally found it! Needless to say I spent the entire night playing it.
Maybe I got carried away with the story, but I'd like to point out that video games (for ANY platform) are extremely expensive in Portugal, they make nearly 20% of the minimum monthly payment of a full time job.
I still play Gran Turismo 3, because it reminds me of a simpler time. I can really go back to it any time, and enjoy it every time. The intro (PAL) still brings a tear to my eyes even today.
Sadly, my technique has evolved too much, and I can't drive at all with the simulation in GT3. The PS2 controller it's too sensitive, and I fail to control the cars, as I'm too much used to GT5 now.
...now ignore this sob story, and just go play GT3, I promise it will make you feel good about yourself!
