The first Evil Game Design Challenge is billed by the good people at Casual Connect as, "The most-popular session in Casual Connect history." (I don't know how they qualify that, but, The Evil Game Design Challenge was definitely the most-watched talk from Casual Connect USA 2013.)
This second Evil Game Design Challenge is much, much better ...
Within the below video, you will find three luminary free-to-play game designers - Ben Cousins of DeNA, Laralyn McWilliams of The Workshop, and Teut Weidemann of Ubisoft - each murdering the game of Minecraft in their own individually evil ways, turning Minecraft out for player acquisition, retention, engagement, and, of course, monetization.
Ladies and gentlemen, I give you the second Evil Game Design Challenge.
