Any suggestions what kind of Amnesia CS should I made?

[FlawlessHappiness]

I think modern custom stories are much scarier than the old fashioned amnesia scenarios. Like in Penumbra Black Plague, when you're in the ventilation tube and from there you can see a guy in a bed and the lights are blinking. You should try it.

That just means that he has to import different stuff to Amnesia.
Amnesia was made as an old-story game. I like making it in the not-so-modern time, because that's what all the stuff looks like.

But you shouldn't make a custom story just because you know what kind it should be.
You need to work out a story first. As soon as you've got a good idea, write it down, work on that idea, and after that... Begin!


Improvement you say?

Light, Billboards, Furniture, all that detailing stuff is SERIOUSLY important.

Also, never make big rooms unless it has a purpose.
Big empty rooms never really look good unless they have a purpose.
