Ohh I like this thread. GT1 is what made me buy a PS1. So....
7. GT Sport - good for twitch, good for e sports. Bad for me. Lack of cars, not really a proper offline mode and....no car parts, the thing I believe made Gran Turismo stand out back in the day
6. GT5 - I think Famine mentioned this earlier, but the economy, at least before they somewhat fixed it (if memory serves), was awful. Plus not a ton of cars. Those are the main reasons
5. GT3 - It was pretty for the time. But missing cars, and just sort of lost that charm and - for lack of a better word - grittiness of GT1 & 2
4. GT6 - Loved this game, but it took a while. Again, a bit sterile I felt. But with updates and all those options for online races with friends, so many memories.
3. GT1 - it hurts me to put this classic as low as 3, because I fell in love with it and it's what made me fall in love with GT. But..it wasn't perfect. The next two on the list are better to play even to this day
2. GT4 - barely. So close to the first spot. It's an excellent game, so many cars, so much to do. I'm gonna use the word sterile again. The only thing holding it back just a tiny amount for me
1. GT2 - Yep. Cars, tuning, parts.....just so much. Probably the top of my gaming memories
I think for me, if Sport added some more features for multiplayer - ways to restrict cars to very specific parameters like GT6, I would've really enjoyed it a lot more
