10 Gaming: 'We'll play games to solve problems'
In the last decade, in the US and Europe but particularly in south-east Asia, we have witnessed a flight into virtual worlds, with people playing games such as Second Life. But over the course of the next 25 years, that flight will be successfully reversed, not because we're going to spend less time playing games, but because games and virtual worlds are going to become more closely connected to reality.
There will be games where the action is influenced by what happens in reality; and there will be games that use sensors so that we can play them out in the real world – a game in which your avatar is your dog, which wears a game collar that measures how fast it's running and whether or not it's wagging its tail, for example, where you play with your dog to advance the narrative, as opposed to playing with a virtual character. I can imagine more physical activity games, too, and these might be used to harness energy – peripherals like a dance pad that actually captures energy from your dancing on top of it.

Pokemon Go came and went and mixed reality turns out to be a detriment to gaming.
Now this did age well from 2011
But nor because we're generating energy while playing 'games' now.
