I know Europe has it's own conglomerate flavor, but as a yank, I'm fairly happy with Gran Turismo. Sort of. Like you guys, I'm hungry to see the series progress into the racing league thing, and I was watching the FIA GT3 thread pretty intently until it fizzled. Many of us are hoping that if Kaz incorporates NASCAR into GT6 he does something with it, but even more so, having all these Super GT, FIA GT, DTM cars, ALMS and LeMans Prototypes etc, provide us some events which are like mini-seasons of these various leagues.
Gran Turismo 3 had such a paltry number of cars that they had to make up for it with racing events, and late in the game, there were events 20 races long to complete, if I recall properly. Regardless, they were very long and quite enjoyable. GT6 really needs something like this. Hopefully, Kaz won't be relying solely on the online championship tools he's going to give us for that.
