First off, go vote.
Second, another analysis of an old game. This one is a wee bit more modern, coming out last summer to generally positive reviews and decent sales. Some people complained about the multi-player, which I never checked out.
It's basically a breakdown for how the game design explores and emulates what's going on in the narrative for a third person FPS. It's all linear and aside from some really interesting options at key moments, the game is all shooting. What makes it so interesting is that the plot is a fairly cynical one about losing your soul.
It's easy to make a game design about being Captain Awesome and saving the planet, it's much more interesting when someone successfully makes one about quite the opposite using the same basic gameplay.
