Using a mouse, keyboard or gamepad make my arm tired, so I can't use them in a continual manner. The only device I can use for an extended period of time is a joystick. It's posing problems when I'm test-playing something in progress.

Even if it's a sequel, lots of people have to give their all to make a game, but some people think the sequel process happens naturally.

Providing accurate portrayals of characters is something I want to pay ample attention to. If I don’t stick to that thought, then we’d have to lower the quality or break the balance of the game. Something that goes way off spec could break the entire game.

I'm not depressed and I continue to remain healthy and positive, but developing 'Smash Bros.' is beyond hard.

You can only truly wow a player the first time he sees [a cutscene]. I felt if players saw the cutscenes outside of the game, they would no longer serve as rewards for playing the game, so I've decided against having them.

The pain goes away, but your work always remains.

In terms of quantity, we've probably already reached the limit of what's feasible. I think a change of direction may be what's needed.
