They just need wind and a plastic bag to create a game, to share happiness!
Designing a good game is never about the technology, the effect, or the platform (media). What a game needs to deliver is a simple way to find our own happiness. It’s all about delivering experience to the player. It’s about providing path, models, and some time boundary to make sure that each player will find their happiness. But there is simple rule about happiness: it tastes much better if we can share it to others.
Therefore, I believe great game designer is the one who can create a game that not only helping us finding our happiness easily, but also remind us to share our happiness with other. Those 3 in the picture are some of them.
