Looked up Ib, but it doesn't look like something that I'd be into.

I'm more into Horror games that seem actually...scary. Not something that seems to be more mystery and stuff, although that's a requirement of a good horror game, I think.

Like...the Vanishing of Ethan Carter. Or Amnesia, or Penumbra. Outlast too.

Or, one of my favorites, the Sunless Sea.
I love anything lovecraftian.

Although, that's probably because I tend to like open world games more than ones with a linear plot.

Might also be because i've also never played a good RPGmaker game that I like.
