Yes, its very Le Mans heavy, but theres a very good reason why, its pretty obvious that due to the way in which it is run, F1 will never be in GT, so instead GT should focus on the next nearest pinnacle = Le Mans.... now before anyone dares to say NASCAR: 1) its already in the game 2) its only big in the USA.... Southern USA.... Southern Most Parts of USA (i think you get what im saying here), the Le Mans cars have more or less served as the 'blue ribband' of GT so it makes sense that PD builds on this and has a thicker spread of cars... not a half-arse attempt with just a few Audis (The Bentley EXP Speed 8 is more or less an R8 LMP), Peugeots, Pescarolos and a sole BMW.
Iv'e said this in other threads and ill say it again, SuperGT's GT500 and NASCAR are the only two disciplines represented properly, DTM(argueably more popular than SuperGT) is very small, GT300 are many cars missing and GT1 hasn't been bothered with since the inclusion of the Corvette C5R and Oreca Viper, PD needs to stop staying in JPN and obtaining more licenses from the likes of V8 Supercars (especially BATHURST), World GT1, LMES, ILMC, ALMS, GT2, GT3, GT4, Superstar V8(yes it is a championship that exists), TC2000(Argentina), etc. if it truly wants to be THE DRIVING GAME.
Please note that by GT1, GT2, GT3 and GT4 i mean the racing categories, not the fricking games!
