I think the gaming industry in general says it. Which is why after 3 Forza's, Gran Turismo is still the driving simulator that Turn10 has to tackle/disparage at every corner. This wouldn't be the case if Forza truly was seen as its own product that stands on its own simulation merits no?
Lets say Forza1-3 was a better simulation than GT.(lol) Why hasn't it turned the Gran Turismo crowd & the PC crowd over to the series in mass numbers? Why did the retail release of Forza2 barely outpace Gran Turismo's "demo" with a console that had a smaller userbase? You know why, and I know why.
Gran Turismo is still the bigger franchise, with its reputation of being a racing simulation & the driving simulation intact even after its 4th installment scored lower than Forza in the media's eyes. Which is why Ferrari choose to debut their vehicle in the game, and why Citroen chooses GT to design a car, why Nissan picks polyphony to deliver the interface for the GTR, why KY himself wins races & puts Gran Turismo fans into driving school to turn around and win races. Yet, we are still here pointing out that while Forza has great features, and is one hell of a game, it doesn't stack up to the universe that Gran Turismo has created. Its just not in the same ballpark, and I think thats what gets under Forza fans' skin.
Im shocked its still going on. You have TURN10 openly lying about the games visuals, then you have the specs of the game, then you have the same exact features from the previous version(community) being touted as the deal sealer for F3(when F2 barely outsold GT5's demo). And you have PD speaking with videos/screenshots which all put forza to shame. Now I see the focus has shifted to GRID's REWIND feature? Come on.
You know this whole thing start(ed) with Forza/Turn10's negative comments towards GT that literally can't be backed up by the game. The only feature that Forza had over GT is its online setup/auctions, which is still the only feature it has over GT. 8 cars & 720p isn't exactly breaking records here.
