A hoax presentation from "McDonald's Interactive" brought the house down yesterday at the UK Serious Games Summit, where game developers met to discuss games that are intended to have positive social outcomes. The pranksters -- widely believed to have been the notorious Yes Men -- gave an increasingly provocative, funny and weird deadpan PowerPoint presentation on McDonald's putative interactive strategy. The presentation focused on the way that corporate practices contribute to global climate change.
