I finally got around to playing Resistance: Fall of Man. While it's not reason enough to own a PS3, it is a very competent and polished shooter that easily exceeds most of the FPS-shovelware you'll find out there (Haze, etc). It also happens to include some of the most intense fire-fights of this console generation. If you're up for that kind of thing, be sure to give it a spin.
