- a dude were modding his DS4-controller by putting the DS3-sticks on it instead of the original ones, he broadcasted himself doing it in Twitch, and when people started watching him, he decided to make a videogame-show with his wife, the Spartan Show where people call in with Gogle Plus and talk.
After it were mentioned on NeoGAF, someone running a show where given away his old PS3, Patrick Klepke called in and they gave a PS4 in prize to someone, and Adam Boyes has called in, Stewart Gilray called in and gave away some Oddworld-codes, and several of them aswell as Shuhei mentioned him on Twitter, and 6 hours later he's closing in on 180k and counting views on his channell with his live-show.
