In my opinion GT6 is, in nearly every aspect, a case of "nearly, but not quite". I'll buy that it was limited by the PS3's capabilities, and at the same time I'd accept that it was perhaps slightly foolish of PD to pursue the technical details that they did in spite of this - but we don't exactly know where the borders lay of technical limitation and resource limitation. I think it's fair to say that many people don't understand the difference between expectation and approximation, and simulation, and since GT is currently on difficult ground trying to integrate more physics into an already overly stretched system, peoples tolerance has worn thin. I would admit to being a little disappointed in 6, but it's not enough to really bother me, I still enjoy the game, and I still play it.... even though it's not quite the game it could be. I'll still support PD based on GT6, because I can't help but think after 5, they started re-building from scratch, and the GT6 is the foundation for GT7 - in that respect, I don't think they have much more to do in order for 7 to deliver what a GT game should. I'll come back to that point at the end, but I'd also say I've never rationalised all the behind the scenes decisions that were the cause and/or effect of releasing GT6 for the PS3 only as it was about to become obselete...
Perhaps I'm easily pleased. It's clear that different people want different things, some want a motorsports simulator, some want an undefined directionless mish-mash of options so they can tailor the game experience for themselves, some just want specific features, to be included. That's all fine, people can want what they want, to me, this is what GT is about:
This... bought to games consoles for everyone to enjoy. And really, I don't ask or expect it to be much different, if I wanted a game to simulate racing leagues, or even give me the chance to compete in one, I know there are probably better options, if I want licensed series, there are other games for that, more in depth physics and all that stuff can be had with the PC titles... for those that do want to take it that seriously. Obviously the more stuff that PD bring in, the more people are likely to be happy with the game, and there are things I'm sure I would enjoy too... but this brings me to one of the things I find so irritating about GTP at the moment. Entitlement. Why do people think it is wrong for Kaz to lead PD to create his vision? The best books, films, albums, paintings etc. are all the product of a person or teams goal to produce something great, to follow through on a great idea, to bring their vision to fruition. If Kaz leads PD to create his vision, and no-one likes it, it's his loss, I'm pretty sure not one single person here had their arm-twisted to buy the game.
So, yes, I will continue to support PD by buying their GT games (and a TT2 if it ever turned up!), and I will probably buy GT7 regardless - simply because I don't want any gaps in my collection. However, I will admit, if 7 suffers the same problems as 6, and is just another "almost" game, I may decide to draw a line there. Most likely I'll be dead by the time 8 turns up, or quite possibly given up gaming by then (assuming things keep moving towards online play).
And, I have to say, from reading some of the comments here, some of you just bought the wrong game, or at best, couldn't be bothered to research it before you spent your money. Remember: not everyone is the target demographic.
