This is still #1 as far as the locations section on this website.  I find that interesting. 

Anyways, I've only played the Resident Evil series.  Is this series worth checking out if I liked RE?

It's a very different game than resident evil. More psychological, but the atmosphere and sense of place is just as strong as Raccoon City, if not stronger.

That's pretty surprising. I would expect Mushroom Kingdom or something to be the top

It's popular because it's more realistic than the mushroom kingdom. Centralia, PA is the perfect example. look on youtube and it looks just like the game,,, creepy

I havent even heard of this place

They're very different. RE is much more physical horror while SH is psychological horror. In RE you have the gore, jump-scares and stuff like that, SH makes you fear the dark, what you can't see, the subjective. It messes with your mind, and that's awesome. Story-wise SH is much more complex and open to interpretation, and so, much better (for me) while RE's is straighfoward a virus made some zombies (not that for all games, but yeah, you get what I mean). I love RE too though, but SH is by far my favorite game franchise ever. Play it if you like survival horror. Start by the first one though. 1 - 2 - 3 - 4 - 0 - 5 or you might get lost in the story.

The series is worth checking out regardless of what you like.  Just try them.

i want to know is silent hill on a hill?

The series is defiantly worth a try.

I had forgotten about Nowhere. That place creeped me the hell out. Then that thing with Lisa at the end...
