Hi there. I saw that both Amnesia and Penumbra are on sale on Steam right now. Is there anyone who has played both that could tell me which one should I buy?
 
I don't usually play games on my computer, but since they launched the Steam client for mac that's slowly starting to change.
 
Thanks.
 

I have yet to play amnesia, but i plan on it considering how much i love the penumbra games. They are soooooooooooooo goood!

At this point penumbra may not have the same effect on you as it would have a few years ago, due to the limitations of the engine.  Amnesia takes everything that was amazing about penumbra and moves it onwards. 
 
In my opinion you should play Amnesia, see if you like the style and if so go back to play the penumbra series.

If I were you, I'd start with Penumbra.
 
That way you can move on to Amnesia later on.

You can get Penumbra: Overture for how much you want here along with 4 other games.  Not sure if they're MAC compatible but you can redeem a code to download them on Steam. 
 
Edit:  Nevermind, sorry, that deal is now over.

Penumbra. Amnesia is the better/scarier of the two, so I think it's best working your way up, otherwise Penumbra just won't seem nearly as good. However, I think Penumbra's story was better. Anyway, if you had to pick just one - Amnesia.

After playing a little of both, I would say Amnesia but get penumbra later If you can.

Thanks guys. I will definitely get Amnesia, but I may have to get Penumbra too.

This is how I'd do it. Penumbra is great, but if memory serves, it's got some pretty rough edges with the gameplay. Also, if you do play Penumbra, play that and then Black Plague. There's a third game that does a little bit more with the story, but not nearly enough to make it worth the gameplay changes. The first 2 are all about the atmosphere and tension, the third is mostly first person platforming and rudimentary physics puzzles.
