The legendary video game designer who created "Super Mario" and "Donkey Kong" has a word of advice for today's industry: Stop nickel-and-diming users.

Shigeru Miyamoto, 65, said Nintendo Co. is exploring different ways of charging people for games, shunning the free-to-play model, which has become a moneymaker in the $140 billion gaming sector by charging players to access additional content. He called on his peers to deliver titles at fixed prices without overcharging players, which would create more sustainable businesses over the long term.

"We're lucky to have such a giant market, so our thinking is, if we can deliver games at reasonable prices to as many people as possible, we will see big profits," Miyamoto said at the Computer Entertainment Developers Conference in Yokohama on Wednesday.
