Now Gran Turismo 5 Prologue has given European gamers their first taste of the next instalment, we caught up with Yamauchi in London. Read on to find out what the roadmap for the game is from here, what he thinks of the competition (hint: he's not impressed) and where in the bloody hell that PSP version has got to.
Eurogamer: The online play modes you've provided in Prologue are pretty simple compared to what other racing games do - is improving that a big focus for you?
Kazunori Yamauchi: Yes, there'll be a lot of features added to that. We'll be adding a lot of the necessities, like being able to form your own car clubs within the game, or making racing teams in the game. Things like that, where the users can actually interface with each other, are something that we'll be adding.
Eurogamer: When you look at the games which have come out since GT4 - with Forza Motorsport probably being the most notable - do you see things that you'd like to do, things that have moved the genre forward? Or do you develop Gran Turismo in a vacuum, ignoring the competition?
Kazunori Yamauchi: The latter is actually exactly fitting, I think. We don't reference any other games when we're making Gran Turismo - it's purely based on what we want to achieve as a game.
Actually, I have difficulty playing other games for over five minutes. A lot of the low-level quality just stands out so much in other games that I can't stand them!
