Suggestions?

[Aloïs]

You should play these:
Pesadelo ( Indie game )
Scp Containtment breach
Slender ( there are multiple slender games )
Cry of Fear
Stalked
The Rake
Mental Hospital
Slender Haunt
Slender's Woods

The most of the above games are not really scary when compared to Amnesia, but still fun.

Custom stories you should play:
Abduction
La Caza
Tenebris Lake
The Great Work
White Night
Poisonous
Emma's Story
Killing's in Altstadt
Through the Portal

Of course there are a lot more good custom stories, just do a little research and you'll find 'em.

Hope this helps.
