Following the overwhelming success of Twitch Plays Pokemon, other developers have begun playing around with the idea of utilizing Twitch live chat to interact with the game currently being broadcast. Twitch Plays Pokemon allows thousands of Twitch viewers to simultaneously play the original Pokemon together via livechat. It's been so popular that Twitch is having issues with the load on its chat servers. Now a developer called Zach Gerlock has put together Twitch Plays Zelda -- and it's exactly what you'd expect, with hundreds of viewers all playing the original The Legend of Zelda together via Twitch livechat. As reported previously, there's interesting moves in the world of AAA game development and Twitch chat too. Blacklight: Retribution company Zombie Studios says that it has been playing around with the idea of Twitch chat altering broadcasting of its upcoming horror game Daylight. Viewers watching a PlayStation 4 or PC broadcast of the game will be able to say specific words into the chat that cause disturbances in the game for the player. Notably, viewers will not be told which words work, and will instead have to discover them for themselves.
