A lot of game critics you talk to will tell you that, after making a career of playing games, it takes a lot to impress them. But that's not exactly the truth.

Perhaps I shouldn't speak for them, but I know for me that all it really takes for a game to knock my socks off is that smallest yet boldest of features: A single great, new idea. I'm not talking about squishing together the dual-stick shooting of Geometry Wars and RPG elements and hoping for the best. I'm talking about an innovation that takes a single step back from the whole idea of what video games are and reapproaches it in a way that feels utterly fresh.

Sleep Is Death is just such an idea.
