Well, 4thVariety, we're all really impressed with the fact that you don't scare easily, especially after you've gone to great length to rationalize all the things that scare a lot of us mere mortals. After you've even threatened readers with being childish if they were to admit to any of these lesser fears, I think we can safely say you won't see a lot of opposition to your awesomeness.

With that out of the way, what scares you personally really is uninteresting to a game developer. What's more interesting to discuss is what scares the majority of us easily-scared children. You will buy one copy at most and the rest of us are going to buy all the other copies. So, perhaps you might want to focus discussing fear in general; I personally think some of the ideas for Dead Space actually address those general fears pretty well.
