Bioshock's more creepy than startling, which I honestly prefer over anything I've seen Hollywood label as "scary" lately... >_> I like being slowly weirded out. I giggled during my run through the game whenever the shit hit the fan. And since it was my first FPS since the N64, and the first I've ever beat without relying on some God Mode cheat or other (really bad at the things), I'm really in no position to judge whether it was "interesting" or not as far as that's concerned, but I really enjoyed it, which is for me a first in the genre. .-.
Creepy creepy creepy creepy. Creep me out, would you kindly?
