Well, I suppose I could be all manly and say i'm not afraid of anything. But thats not necessarily true. Sure, I don't think I have any phobia's, but I guess i have the same basic fears as everyone else. Being eaten alive. Thats a pretty scary prospect, no matter how you look at it. Well, being conscious and eaten alive. Knowing that that animal is eating YOU. Not just a random piece of meat, but you. A part of you. And you're powerless to do anything, feeling every piece of yourflesh rip, hearing the crunch of your bones.. Christ, that ain't something I'd wanna wish on anyone.
Being burned alive too. And everyone has a fear of the unknown. Depending on the situation, usually. "If you look long into the Abyss, the Abyss looks into you."
I can't say a game has ever "Scared" me though, sure, they make you jump and such, but I've never been scared to walk round that corner, face that beasty etc.
Remember kids, courage is not the absence of fear.
