DIdn't anyone ever thoght that they PD (or manufactorers maybe) does not want livery editor?
Didn't anyone notice that GT series does not even have an option to paint your car after one purchased? And that all cars are coloured ONLY in official colours (with respectable names for each colour)? Didn't anyone thought it is deliberate?
Only "Dream Cars" class features non-existant liveries on race cars class. However, in GT4, Dream Cars class has almost dissapered in behalf of official liveried cars. Maybe there is a reason for it too, don't you think so?
Personaly, I have nothing against livey editor, but after some time I wass totaly pissed-off because I was the only one racing normal-colored car while being surrounded by naked chiks with spreaded legs and similar childlish painnts in FM2 online.
So, my vote goes to maybe having option for numbers on the doors (as seen in Tourist Trophy games and announced for GT series in some point) for some cars, and leave the option to create an manga-anime-childlish-porn all over F430 out of GT series. Forever.
