Like everyone, GT1 was where it all started for me. I saw Gran Turismo set up in the local K-Mart where I picked it up and had a go. I was rubbish because I was not a computer game player but loved cars (no, I never even had an Atart 2600 - my brother got that). So GT1 got me hooked on computer games as well.
I remember saving like mad for a PS1 (remember, they were really expensive when they came out) and finally got it, only to realise I needed another controller and a memory card and the game. That was an expnsive day.
I played the game and played the game until I knew all the menus back to front and I could actually strat the game and leave the TV off and navigate my way into a race menu with the TV off from the repetitive playing. I was reading some of the responses out from this thread to my gf and she remembers GT1 as well. She was, I guess you can say, a Gran Turismo widow.....! (We are still together)
Favourite moments for me were seeing the intro movie in aboslute awe and wondering if perhaps, one day, they could make the game graphics that good. And of course they did that with the release of the PS2! I adored the massive range of cars available, and I also loved that there were 'ordinary' cars available - not just top level supercars like in every other game ever made, but real cars like Civics, Lantis' (in Australia Mazda 323s) etc all the way to Corvettes, Vipers, Skyline GT-Rs, Supras, NSXs and then the most awesome Supra Castrol GT race car.
I got to the point where I had played the game so much that I knew where the best replay camera angles were so I'd drive a clean couple of laps and deliberately drive a specific angle to ensure the replay looked realistic. The High Speed Ring gave some great static camera shots for this. In addition, Laps 2/3 on the Grand Valley course gave an aerial view looking down across the start finish line which I always liked.
My favourite car was a gun-grey R32 GT-R Nismo road car after I'd lightened it, added racing brakes and added super soft tyres (but left the power standard). I could destroy Vipers and the like under brakes and through corners but had to try to hold them off down the straights. I also really enjoyed the Pulsar/Sunny GTi-R (where has that gone Polyphony?)
I could never keep the NSX in a straight line under braking so steered clear of that, thought the Mitsibishi GTO was too heavy in standard form, loved the FTO in race form, and loved the Castrol Supra race car. It had the best sound when the speakers were turned right up and you were in time trial with no other cars on the track so it was your own engine echoing around the circuit. The TVR Cerbera race car was one of the fastest cars on the game - around the High Speed Ring it was magic. I really loved the Nissan GT-R LM cars (Clarion and the Keep the Dream Alive) but their absurdly bouncing suspension was frustrating, if challenging. I found that certain tracks were off limits to that car - Trial Mountain was just too painful with bouncy suspension.
The greatest moments came of course playing two player. A friend and I lost many weeks of our lives playing against each other. We'd invariably drive Grand Valley (the full circuit which is a favourite right through to GT4) and have something like a Supra road car and an RX7 Series VI road car - all of our races were road cars because they were a challenge with a lack of grip but also because we considered road cars the most fun. That first corner would usually see one of us end in the sand trap at the first corner hairprin whereby we'd have to restart the race. In the end it was easier to agree not to race too hard until that first hairpin was out of the way, or if one of us went off, the other would wait, then we'd line up and count down together from a standing start. These standing starts would even be done no revs or full revs, The no-revs starts would be useful in working out which had the lower gearing and best acceleration. The STi Impreza and Evo IV roadcars gave great races - particularly around Deep Forest.
I got gold in every licence and got every car including the TRD 3000GT Supra (what a disappointment) and the Nismo 400R. I lived and breathed GT1 and the only thing that could have been better was the imminent release of GT2.....
I went and tried GT2 the other week and was stunned at how hard it was to keep on the road with savage car movements under braking. I recall that GT1 was even worse. The pixelated gra[hics also came as rude shock and I remember them being state of the arts and unreal on release. How quickly we adapt..... It has been years since I've loaded GT1 up. I don't know if I could do so now because I don't want to be disappointed. I'd rather remember it as a game that was ahead of its time, revolutionised an entire genre, introduced me to computer games (which I followed up with a PS2 and now PS3 - all due to the GT series only), created entire online communities like this one, and brought friends together in front of PSOnes and TV's across the globe to play arguably the most groundbreaking car racing game ever made. Every subsequent Gran Turismo release owes something to the original. It has been a real trip back through memory lane recounting my experiences in this post. KY has brought a lot of joy to a lot of people.
