Next game: My ideas

[Tiptoer]

Honestly it doesn't matter what the enemy is, a human or a demon dog, it's the atmosphere that determines whether you're tense or not. Take Call of Cthulu: Dark Corners of the Earth. It just had a very creepy setting and the right atmosphere so footsteps from humans could potentially scare the hell out of you, well along with ancient bipedal fish monsters.

I just found out about Frictional games but I do hope they have something ocean related because humans really don't know that much about what's in the oceans.
