At this years REPLAY stand, I wanted to show off a fun one-press game. I've played such games before, like the one-press version of Frogger, which to be honest is not huge fun. The mini-game of duck racing in Shenmue, although pure luck, is fun.
A single press of a single switch rolls an adapted electronic die. The number that appears is the duck that is selected by an assistant taking charge of the extra controls and the race started (with a second press if desired). People had a lot of fun with it. There aren't enough bow-tie racing ducks in the world I decided.
