Ah simpler, pre-internet, times: when screwing up someone's perfect game was as easy as "accidentally" tripping over those absurdly short controller wires during a pal's perfect Sonic The Hedgehog run. Choice Chamber, the first title funded in part by game-broadcasting juggernaut Twitch brings that sort of griefing into the modern era and it's out now. A brief recap: while playing the game and broadcasting it on your channel, the audience in chat has a direct impact on what happens next in the 2D side-scroller. So if I'm feeling particularly nasty, I could set one of the game's procedurally-generated rooms on fire and give someone's player character the pogo ability, which makes them jump around all willy nilly. You know, if I was in a dour mood and could get the folks in chat to agree with me (I am very charming).
