Gran Turismo creator Kazunori Yamauchi has hit out at driving games released since Gran Turismo 4 in 2004, saying that the 'low level of quality really shines through'.
In an interview with Eurogamer.dk, Yamauchi was asked whether he may implement features from different games in future Gran Turismo games, he replied;
"Actually I find it difficult to play the other games in more than five minutes at a time. The game's low level of quality really shines through in the other games and I can not hold them out!"
You'll have to wait and find out whether Gran Turismo 5 lives up to the standard of the incredible series when it releases later this year in Europe and America.
