Played it: Metal Gear Rising: Revengeance
On the subject of video games that aren't ashamed to be video games, the superbly titled Metal Gear Rising: Revengeance is a prime example. Living by the rule of cool, the cyberpunk themes are plundered for diverse enemies that blur the line between the biological and the technological - in the process covering more interesting topics than the "cyborg modification is bad - yes/no/maybe" of certain other games.
Revengeance doesn't take itself seriously. It's happy to use the language of video games and it doesn't mind looking silly from time to time if it benefits the overall experience. The gameplay is frantic and fun and, on normal difficulty, I thought a little easy... At least until I reached the final boss battle, which starts out with a giant spider mech trying to stamp on you and only gets more extreme and challenging from there. I emerged from this final onslaught a little like its hero: worn out and pushed to the edge, but mostly just satisfied to have splatted a bad dude and a few hundred of his mooks.
