Valkyria Chronicles has running and shooting, but it's a strategy game and not an FPS. (VC is the # 1 game that I'd recommend to anyone with a PS3....in case you couldn't tell from all the references in this thread.) If the game has to be an FPS, you might want to take a Look at Resistance 1&2 (haven't played personally). If you just want to shoot stuff, and don't mind some occasional deviations from the running and shooting, try out Rachet & Clank Future: Tools of Destruction. (The game looks beautiful on an HDTV, and is just fun.) Uncharted: Drake's Fortune is a another shooter-esque game, but comes off as more of an improved Tomb Raider game than a pure shooter, but there's still quite a bit of gunplay (again, haven't played). I've heard mixed things about the PS3 version of SOCOM, but that's another title you may want to look at if you're that into multiplayer shooters. And I would be remiss if I failed to point out that Call of Duty: World at War is based on the CoD4 engine. Finally, if you haven't played it on PC (or 360), you're getting a ton of game for your $ by picking up The Orange Box. Team Fortress 2 (great multiplayer FPS), Half Life 2, and HL2 Episodes 1 & 2 (single player FPS), and Portal (first person, 3d comedy/puzzle/platformer) all on one disc.
