Depends on what you mean by "scary." As for the poll, I chose "no." I do hate to be embroiled in semantics, but here goes:
Startling is when something jumps out at you. Scary is when something jumps out at you, then tries to eat you. Horror is something completely different.
Look, I am an Irish-American, so, I am scared of snakes. St. Patrick ran them all off the island more than a millennium ago, and the collective Irish sub conscience has not had to deal with them since. So, the common way to scare me -if someone was to build a game solely directed at me- would be to put a snake in a cupboard somewhere and have it jump out at me at some point. This is starling, it might even be scary, but it is not truly horrifying.
A truly horrifying game, like Silent Hill, would not bother to do this. It would simply lock me into a filthy, rusty room with a picture of a snake, and tell me that there may -or may not- be an actual snake somewhere in the room with me. For extra points, they could tell me that if I stared at the picture of the snake for long enough, the real snake might go away.
This is truly horrifying. Real horror always looks inwards to its characters, and inspires the audience to do the same, and to confront the truly terrifying inner fears, sins, and insecurities that we all have. Most "horror" now-a-days doesn't even have the characterization of a Jr. High creative writing paper, let alone enough to inspire the audience to look inward.
