I played GT4 for a few days, and was just magnificent! The resolution was terrible, but I didn't care of it at all. I took the Formula GT, did some laps on some of the missing tracks & I have to say one thing:
We are "walking" on the period of GT6's growth and based on the theory, GT7 will take many, many months to be released. If some of you remember, GT5 was on the same condition after it's release, BUT, we saw many big updates that brought new cars, new tracks, new features and as a result, Polyphony built a very big group of GT fans in the PS3 community. I'm sure that PD wants to do the best for this group of fans (I don't want comments about that please! We all love Gran Turismo, because some people wanted and continue to share with us the same big love we have too: the cars). I also know that many people got frustrated about PD's lack of responsibility, and (unfortunately!) left GT for something else. GT6 needs some characteristics, that made the older GTs memorable. PD has enough hardware, and a re-make of some tracks (SSR11, Mid-Field, Seattle etc.) or cars (TS020 Road Car etc.) would make things even better for all of us. If K.Yamauchi decide someday to answer the question of this thread, I hope he will consider it, because I believe this is a good way to make Gran Turismo an even better simulation than now...
