A good idea is something that does not solve just one single problem, but rather can solve multiple problems at once. - Shigeru Miyamoto

I think the first is that a game needs a sense of accomplishment. And you have to have a sense that you have done something, so that you get a sense of satisfaction of completing something. When I approach the design of my games, what I have to think about is how I'm showing a situation to a player, conveying to them what they're supposed to do. In Mario you keep going to the right to reach your end goal. In Donkey Kong you keep climbing up to rescue the captured princess. The last is the immersive quality of the game being able to feel it's a world you're immersed in, that you've become a hero. That you've become brave. Even if you're actually crying.

Controller is so intuitive, even your mom can play.

When we’re doing an action game, we make the second level first. We begin making level 1 once everything else is completed.
