Dead Space isn't an FPS per se, but there's a lot of shooting involved. I grew up with FPSs and although the over-the-camera perspective is a bit annoying at times, I tend to forget about it when I'm shooting something. Overall it does a great job of immersing the player in the game, it's very stable, there are definitely some cool features (alternate firing modes, weapon upgrades, dismemberment), and it's damn creepy. I'd recommend it. It's the only game where the only thought in my head is often "Kill it! Kill it with fire!"
