I'm a bit late to the party, but Unmanned is probably one of the best games I've played in a while.
It's a fantastic use of interactive fiction / first person sensibilities (some of which I'm going to steal) with innovative use of split-frame and achievements, contemporary relevance but also rather personal narratives... it's got everything.
If you're upset that it's not subtle enough, consider all the noise it's trying to combat, all by itself. You don't bring a toothpick to a knife fight, folks. Also, in case you missed it the first time, check out this game's distant cousin, "maybe make some change."
Funny how similar the premises of these two games' methodologies are: that text and only text can adequately communicate the psychological damage of modern warfare, and militaristic first person games thrive on the lack of text and introspection.
Pop music doesn't care whether you think it's authentic, though.
