In all honesty It does not matter if it was in a joking manner, its manners 101 not to make a joke that could come off as disrespectful to a superior or a stranger, only someone you know on a personal level. I still think the question was rude (though if a full understanding was met an apology is unnecessary) and it could have easily been taken the wrong way. The Japanese take there jobs very seriously and to say if he wins can he help balance the game makes it sound as if he thinks the game looks unbalanced and is in need of outside help (which it is not). Another problem I have is that people say that Sakurai is unable to make a competitive game, when it is in fact the opposite. I am sure he is capable of making a game that is competitive but he is not worried about making one. He's obviously more focused on other parts of the game than to worry about making a game competitive, he gave you for glory with your FD styled maps and no items, why worry about the other things the game is not so unbalanced that one fighter has an advantage over another. The mode is a level playing field that leaves it up to you the player to showcase your own skill to adapt and win. He does not need to change anything else with the game, it is balanced fine, no one character is at anymore of an advantage than another, if you can't make it work than it is you who is lacking in skill not Sakurai lacking in ability to make a game.
