I've read about Vision Gran Turismo for the PS3 and I must say I was very impressed.
Here's what I'd like in Vision Gran Turismo (provided this working title is a stepping stone towards GT5 and made for release with PS3)
My Vision Gran Turismo
Maximum of 20 cars per race, even if all these cars are open top with the driver showing, in single player race
Maximum of 10 cars in 2 player split screen or LAN/online race (allowing putting in AI cars along players to go up to 10 cars)
2 player split screen/LAN/Online replays and the ability to save them (also to watch them full screen and use garage cars)
2 player split screen/LAN/Online drag racing
Ability to open doors on certain cars as a special feature in photo mode (this being the cars that are already shown with the doors open in GT4)
Ability to turn on headlights while racing, ability to put open top cars roof on or off while in garage, ability to leave skid marks or tyre tracks, ability to get the car dirty (with particle effects similar to Rallisport Challenge 2)
Make all spectators 3D and motion captured as well as pit crews, marshals (similar to the E3 demonstration)
Simulated damage based on an icon system, but nothing visual until GT5, at the end of the race the car is repaired and the credits are deducted depending on the amount and type of damage (similar to the icon system depicted in Forza Motorsport)
Improved physics and realistic depiction of car collisions, but without cars flipping until GT5 (unlike GT4 car collisions which are very unrealistic)
Improved AI (only if theres an easy way to do this and not to time consuming)
3D wheels
All the bugs, glitches and problems from GT4 corrected (one of them is the wild fluctuation of stated power in different screens and game modes)
Wider range of rear spoilers and also front spoilers (ability to have the spoiler in the colour of the car also)
All the cars that were left out of previous GT games available in the used cars section and available at random and in random colours, split into 70, 80, 90, 00 (only if there is an easy way to do this and not too time consuming)
A 3D scripted Dyno feature stating the current power figures in the GT auto section
Improving every track replacing any sprites with 3D models and generally improving the overall look
Improving all the cars (only if there is an easy way to do this and not to time consuming)
Thanks for reading, my long post. What would you guys like to see in Vision Gran Turismo? Do you think the things I've posted are possible by the time of the PS3 release? Will it be enough of an improvement for you to buy the new game?
