I was going to make a similar topic but since you have posted this one I'll just go ahead and add mine here
This list contains all the Custom Stories I've played along with its rating (of course from my point of view) Of course I'm looking forward to play more custom stories but I'm taking a break now to prepare myself from the new amnesia (machine for pigs). Also I think I played all the main ones but if you have any suggestions I would love to check them out.

as you can tell from my list I prefer the custom stories that add a little bit of different vibe by using the penumbra maps and textures. And quiet honestly my favorite will always be white night even though its not really THAT good compared to other stories which have so much action but im so much into psychiatry thats why I liked it
Sorry for the long post and bad English.
