From
EDGE Online:
The PSP version’s been a long time coming. What challenges has it posed?
There were a lot of obstacles: the small screen, the lesser CPU power, the lower graphics processing power, and the small amount of memory. We went through and checked out a lot of the other racing games on PSP, and there’s not a single one that lives up to the
Gran Turismo quality. We had to work very hard to get it to that level.
So what makes a GT game on PSP?
All of it, really – there was an unbelievable amount of material that had to make it on to this machine.
As a percentage, how much of Polyphony is working on this version, as opposed to Gran Turismo 5?
The balance varies from day to day. A lot of companies, when they make a PSP version of a game, license the development out to another company. There were times when 100 per cent of our efforts were on the PSP.
There was quite a debate about it at the time, and a lot of resentment that GT PSP would delay GT5, possibly a year or more - it did. The other stuff I posed as my opinion. You might note that I specifically mentioned Kaz hasn't discussed any of it. And I don't have telepathy or his personal email addy.
