It will look the same realistic at 720p.The reason why the game looks in 720p worse that in 1080p is just because game is made ONLY for 1080p mode and in 720p (or other) mode(s) game uses hardware bilinear filtering on textures to scale them down - that caused in blurry textures.Also even digital RPM gauge looks distorted at other than 1080p resolution.And worst of all PD didn't fix that.
I mean why the game looks so realistic is not depended on resolution.It's game graphics engine build that way.
That's not the case. The game looks more blurry due to your TV screen. Some TVs / Monitors do better at showing lower resolution content on the screen, you will know what I mean if you lower the resolution on your laptop or PC and you will see it will look blurry. If your TV native resolution is 1080p then it will look better but I believe 720p has more anti aliasing than 1080p in GT5 but the sharpness of the 1080p will compensate for the lack of the extra anti-aliasing.
There might not be a GT6 because if you think of it ECONOMICALLY from a BUSINESS point of view, GT5 has taken 5 years and cost $60 million to make, if reviews aren't good and the sales don't live up to hopes then Sony may decide that such a costly game with such a lengthy development time might not be viable for them from a business perspective.
Think of it, what would you rather have? A promising new exclusive title or a franchise in its 5th instalment thats cost a hell of a lot more? Chief execs in Sony won't be 100% clued up on gaming and won't take a good view on this, sounds very ridiculous but the axe may loom for GT if the sales aren't good/profitable.
GT5 has good reviews considering many reviewers are taking pot shots at the game due to lack of understanding of the development time.
In that time, they have released Tourist Trophy, Gran Turismo PSP and GT5 Prologue.
In comparison to it's rival on the other platform has released Forza 2 and 3, Forza 1 released at a similar time to GT4.
The only thing carried over from previous GT games are the GT4 cars and they have been remodelled for the PS3. The rest is built from the ground up. Forza physics engine has been built on top upon Forza 1 I believe while GT5 is a completely new one. I'm actually suprised how fast Polyphony Digital can develop, I think they are the fastest in the business. People don't see the bigger picture so they will throw insults at Polyphony even though, the staff must have worked day and night at times to get the game ready for many years.
About commercial success, GT5 will most likely be all profit after the costs of advertising and cost of making the discs are paid for. GT PSP (Assets of GT5) and GT5 Prologue have most likely paid of the development cost of GT5.
I rather have 200 odd premium cars which are ready for next-gen, i.e. modelled inside and out than have 1000 standard cars with added on cockpits, similar to what Forza 3 cars, standard cars (Forza 2) with added cockpits. It is a waste of development in my opinion as they will scrap the cars next-gen if they want to keep up. GT5 is a game for future iterations to build upon. I belive GT5 work will take until GT7 to show how far they are ahead of the competition if it released on PS4. The car models are really amazing detailed. If Sony were to make a console now, the actual power of the console will be at least 6 times more powerful using mid-range parts and 10 times with high end parts. This will double if they release PS4 in 2014 and the console will most likely be 14 times faster than the PS3. My mid-range laptop I bought for £300 used in 2007 plays multi-platform games better than my PS3, it's amazing they can push 60fps at 1080p on such a console.
Other games like Grid and Forza are only made to last this generation, in terms of car detail. They will have to reinvest next generation to get near the quality of the GT5 Premium cars.
Also axing the GT franchise is equivalent to suicide for Sony, it has always been its biggest selling exclusive and if the GT5 sales match GT5P then it still will be this generation. It is a cash cow for Sony and moves consoles and sells many copies. Don't get disilusioned by reviewers who would want to make you think GT5 is a failure of a game, when most of this reviewers have had 4 days, some have only had it for a couple of days. You have to be superman to review that game in 4 days for such a big title such as GT5 and the online component has only really gone fully live as of today.
There are a lot of double standards going on if you read the reviews of other games by the same reviewer. The things they use to bring the game down on that are worse in its competitors are not even mentioned and quite a lot of reviews should be only previews as they don't even touch on many of GT5 features.
I don't mind if the reviews are negative, as long as they are justified, not because it was in 5 years in development or it cost $60m to make as a negative thing, and add things like countless delays when there have only been one in US. The other thing is not even reviewing the online component of the game when it is quite a big expanded feature for the GT series.
