Ten interesting ideas in videogame construction

The Guardian Unlimited's games blog recently ran a feature on ten interesting ideas in videogame construction. The ideas aren't new, but they are mostly ideas that have only recently been attempted / possible.

Many of the ideas would lend themselves particularly well to Learning Games, such as the idea of emotional gaming for something other than sex (perhaps to provide empathy training for young children or corporate executives) and personalization that has an effect on the learning landscape (imagine a game set during the civil war that plays differently depending on the skin color, clothing, and sex you choose for your avatar).
