I don't have many info about atcual content or such to be honest, but that is not important for this topic
Although I find this poll and overall idea very constructive, I do not see why option to vote for "Gran Turismo game as it always was" is not included.
I would never like to see Gran Turismo becomes just "another" racing or driving game as all outhere - including dull and boring simulations with no soul whatoseover. Hopefuly it will never happen, but it's very unfair to give people option to vote about what they would like Gran Turismo 5 to be and not include simple and for some the best answer "just Gran Turismo".
You somehow made all your poll-options very unfair, while creating confusion in overall idea - because it's not clearly visible that your options ARE NOT regarding PHYSICS syle, but GAMEPLAY style - which is totally diferent idea.
And also you're making options very biased in your subjective descriptions.
1.
Hardcore racing simulator (ultra realistic and as many IRL race tracks as you can think of) - you're presenting this as the "greatest option", but that's just your subjective oppinion.
2.
Racing simulator (decent simulation not quite like the leading PC ones) - this shows the bias you've expressed above, because you clearly say that other simulations besides PC are not "simulation like the leading PC ones". I do not want to go into another meaningless debate about what is simulation and what is not, but you're clearly biased here.
3.
Racing game (just like the random kid racers such as Forza, PGR, NFS and so on) - calling these games "kid racers" is somehow offensive because of the reasons I have no time and intention to discuss - but it is also clear showcase of your bias - and it also shows that you've also mixed fundamental idea about PHYSICS and GAMEPLAY structure design
4. Driving simulator (race tracks included, but also free roam in cities) - no problem here
See my point? It's that simple
