gt5 is an awesome game, this is a fact. the car handles AWESOME, and the features are nice, especially the web related features. and the effort from PD taking the original sounds from each vehicle is awesome, but still, eseveral areas they can improve.

1. Bring back brake upgrades.

2. The ability to tweak your gear ratio. This is important if you are aiming for the top speed vs  quick acceleration thingy. GT4 did well  in this.

3. Standard  cars needs some sport rims love. I got  Evo 6 TME  that has the rims like on those Nissan 120y. had to sell the car for that. Painful.

4. Rewards for online racing,  like more money (like those in GT5P, trophy or a spec points) now I  concentrate my effort offline. unlock more  tracks, more money and raise my a  spec level.  other than fun with friends, I dont really see a point going online.

5. Continuous support. Criterion did well wiith Burnout Paradise and now, NFS Hot Pursuit (even to the game feels  like Burnout)
