I found a very interesting game concept today on kickstarter. It takes the concept of Twitch Plays Pokemon (though it was being designed before Twitch Plays Pokemon became a thing) and allows your audience to change different aspects of the fighting type game as you play. I’m loving this idea.
(I’m not sure how to do the fancy imbedded video. . .)
Also they are doing a 48hr interactive livestream/hangout here: Twitch
