After playing Amnesia, is Penumbra any good?

[Crabski]

Absolutely. Penumbra is a MUST play!
I enjoyed Penumbra more than Amnesia, to be honest.

...and I say it straight about Requiem:
If you wait the same than from Overture and Black Plague, you dissapoint. But if you wait the same than from Portal, you love it!
I liked Requiem. Mostly because I knew what to expect. Others waited for more horror... I wanted more puzzles, and there it was: Requiem.

I'll do the fluent English speakers here a favor and clarify this a bit more (no insult intended, just so everyone can understand).

Requiem is a puzzle off-shoot with little to no horror in it. It's much more similar to Portal then it is to the other Penumbra games; so don't expect it to be something it's not!
