Penumbra Prequel made in Amnesia

[Googolplex]

Penumbra is scarier than Amnesia. The mine in Overture is really more earnestly compared to Brennenburg castle and that makes the horror.
In Penumbra I don't feel like to be in a game. In Amnesia, you feel like in a game. That is a horror no-go.

The problem is, that Amnesia has flashbacks which will pull you out of the immersion, and that the environments are less complex and less seriously. Amnesia is more melancholic horror, a contrast between creepy and sissy. And that works good, but it was by far a smaller experience like Penumbra.

I mainly praise Penumbra Overture for its well made horror setting. I felt like to be alone in a leaved mine and that the danger is behind every corner. I really was immersed. Amnesia also has this feeling, but not as much as Penumbra.

So it's totally wrong when you said Penumbra environments are less scary.
