Lets see... what would I change:
1) The A.I Although it's been improved, it still gets anoying sometimes. That double or triple braking that the A.I does at the middle of fast corners has to go. Not everyone plays online, so to have a game that works in this aspect for solo players would be appreciated. Or at least they should put an option of difficulty like "Beginner - Amateur - Professional" so all levels of GT players can enjoy the game.
2) Prize system: The prize system that GT4 had was probably the best. It would be good to have a prize car at least in championships no matter how many times you do it. The ability to sell any car. A limit of maximum Cr. like GT4's 265k limit would be ok. The price that some cars is exessive, and it's not like they are unreachable, but grinding for them isn't as fun as it used to be. It's fun for the first two or three million, but after that it gets too much of a hassle.
3) Rally events: Rally became part of GT since GT2 and it was always well recieved by fans. Again, GT4 went far and beyond to deliver the best rally experience in any other GT title, though it was not actually like a real rally. GT5 nailed it with the "stage type" rally events, even doing something so cool like adding a co-pilot (something never expected). But again it failed on delivering a purpose to play these events more than two or three times since there is no incentive to repeat them other than for the fun factor. Unfortunately while I enjoy them alot, everytime I want to restart one, I think to myself
"I should be grinding seasonals or Indy to get Cr. and exp, intead of loosing time repeating a one hour event that doesn't give me anything." Which is sad... And this takes me to my previous point: Prize system. Every event should give a fair amount of Cr. and Exp, plus a prize car so you're not stuck doing the same events when you need to buy an expensive car.
4) Championship save: Like in previous GT titles. If they gave us Endurance save, then why not championship save.
5) Better use of tracks: A-Spec events lack of variety. It's either Rome Circuit, Monza or the Ovals. There are many tracks unused and many Championships and events that look like the other one. Example: Muscle car "championship" is only a single event in Monza(?!) what does Monza has to do with American Muscle cars? They don't evn run fine in that track due to their short gear ratios. Dream Car championship, Like the wind, All Stars and GT Championship feel exactly the same, and have pretty much the same type of cars. Modern Muscle car championship only has two events, where it could have at least five since there is more than two American tracks. And the list is endless. Again, GT4 was much better in this aspect.
6) Manufacturer Events: They should be back. Just when you though you finished the previous GT's, you went to the dealership and found these special events waiting to be completed. A lot of fun!
7) B-Spec: While I think it wasn't a bad idea, it was poorly implemented. Instead of making it like a "interactive replay" section, why not implementing it like in (again) GT4, where it was actually useful, specially in endurance races. It would be cool if they did a couple of "B-Spec only" special events, but not a whole section that takes half the carrier mode.
8) Liscence Tests: Although the leveling system works, the game desperately needs the old system to be implemented. They could leave the level system for adquireing cars only so people don't go for a Veyron after finishing the Sunday cup, and the classic Liscences to access more events. The game feels more authentic like that. Liscences are a classic feature in GT and one can't help to feel bad because they are actually meaningless in this game...
This is pretty much what I think it would make GT5 a better game. I will not suggest anything regarding new cars/manufacturers, wheels, aero parts, or the whole standard/premium thing. It's easy to just say "give me a Gumpert thing, an Ariel whatever, premium Veyron, Aventador here, Huayra there..." when those are things that really don't make the game a better game. NFS Shift has some of these cars, and the game is unfortunately a bad experience... Forza has some of these cars, and although a good game, it doesn't deliver the feel that GT does. Plus we know how long it takes for PD to make a car.
My opinion, so don't go crazy over it
