should i get penumbra if amnesia scared the sh*t out of me?

[Googolplex]

Penumbra does not have pictures of men hung upside getting sawn in half. It has nothing as disturbing as the torture rooms, not really anything to compare to that either.

The separated head in Black Plague, the separated hand, the embryos of Infected, the monsters itself, the mental realm horror parts etc.

Horror is not to show how someone gets tortured, horror needs a bit more to be effective enough.
Amnesia was EXTREME scary, but the feeling of "danger" was an important aspect in Penumbra.
I never felt save in Penumbra, and the infected (especially the one in the computer room) are the scariest monsters in Frictional universe. Amnesia was more cruel, but Penumbra was more brain paranoia.
