Tom Chick - "The essay written/designed into Afghanistan ’11 isn’t just about American history. Afghanistan ’11 learned a lot from Vietnam ’65 about gameplay density. It’s less of a slog through a jungle and more of a helicopter ride over the mountains. More happens. More options for meaningful decisions. More roles for more tools. Units move farther and can do more. More action, less waiting. More systems threaded smartly into existing systems rather than bolted onto the margins. This essay isn’t just about the changes in war since Vietnam, but it’s about changes in game design. Nagel also honors his new profession."
