Yeah, Thief is not an FPS. But didn't I use the System Shock example already? Maybe you didn't understand how much of an FPS it actually is. It's an FPS, I tell you. You go around shooting things. You pick up a weapon. You use it to shoot bigger and nastier things. Now and then, you pick up a piece of hardware, the called cybernetic implants. Those are nothing more than equipment. No RPG elements involved. You don't get to improve your character's stats or skills. Quite often, you find audio logs and recieve emails, which tell you parts of the story happening at the Station. Unless a good story is considered an RPG element, I can't see this game as anything more than an FPS. Still, it's so much better than Quake, and so different, that it's hard to believe both are based on the same principle. But they are. The main difference is that SS is at a much higher level of enhancement.
