A delayed game is eventually good, but a rushed game is forever bad. - Shigeru Miyamoto

Necessity is the mother of invention. I love solving things like that. Because there wasn't enough memory, thinking of an economical way to make the movements look right was like solving a puzzle, and I had a lot of fun.

I don't know what Mario will look like next; maybe he will wear metallic clothing with a red hat.

Challenge for the player is the most important thing. In the Mario games for example, the player can go back and try to finish the game without collecting a single coin. I think great video games are like favorite playgrounds, places you become attached to and go back to again and again. Wouldn't it be great to have a whole drawer full of "playgrounds" right at your fingertips?
