The passionate demands of hardcore gamers can be overwhelming, says Nintendo’s Reggie Fils-Aime.

Reflecting on the reaction to his company’s E3 press conference, Fils-Aime said he was conflicted over the reactions of Nintendo’s fanbase.

“One of the things that, on one hand, I love and, on the other hand, that troubles me tremendously about not only our fanbase but about the gaming community at large is that, whenever you share information, the perspective is, 'Thank you, but I want more.' 'Thank you, but give me more.' I mean, it is insatiable,” he said.

"For years this community has been asking, 'Where's Pikmin?' 'Where's Pikmin?' 'Where's Pikmin?' We give them Pikmin. And then they say, 'What else?' ”

He said similar reactions greeted the new Mario brothers game as well as Nintendoland.

"I have heard people say, 'You know, you've got these fantastic franchises, beyond what you're doing in Smash Bros., isn't there a way to leverage all these franchises?' So we create Nintendo Land and they say, 'Ho-hum, give me more.' ”

“It's an interesting challenge."

Fils-Aime also felt that fans were too harsh on some titles that wound up being huge successes.

“When we show a game like Brain Age or when we show a game like Nintendogs, what's the fan-based community reaction? 'Ho-hum.' Until it sells millions of copies.”

He singled out the initial reaction to Wii-Fit, a much-maligned product that went on to sell 43 million copies worldwide.

“I would argue that the gaming community actually is unable to differentiate between a phenomenon and something that is 'ho-hum',“ he said.

"Until they play it. Until they experience it. Until their friends and their non-gaming associates say, 'Hey, have you seen X?' "
