Changes Afoot in Gaming

As you might have heard, XBox chief Peter Moore resigned.

A few questions about gaming:
1. What are the characteristics of an ideal game?
2. What's more important being able to physically move as you control the game, as in the Wii, or graphics, as in nearly everything else?
3. In a decade, after virtual reality, or augmented reality games become popular will anybody still want to play the games that are popular today? Why/why not?
4. What will video games look like in 100 years?
