Nintendo's Developer System games could cost as little as 3800 yen (about £18) when they retail in Japan, according to Yukihito Morikawa, President of Japanese developer Muumuu.[br]Writing on his company's website, Yukihito-san said that he believed DS games would retail for that amount, but also went on to criticise the price because he felt it limited developers' freedoms and that for smaller releases, it would prove too expensive.[br][br]Muumuu is a third-party developer which has produced a number of games for Sony - including the Jumping Flash! series - and is also thought to be developing a new title for Sony's PSP. [br][br]However Morikawa-san's comments are a long way short of any official announcement, and of course Nintendo won't confirm any pricing information on the DS or its games right now.[br][br]However it is an interesting 'ball park' kind of figure for what DS cartridges might eventually cost and would seem relatively credible, given recent speculation about the price of the console itself.
