I think it would be good idea actually.
It gives more popularity to amnesia and greater audiences for people's custom stories and possibly mods.
I think it would be a very good investment though it would probably need a proper marketing campaign along with it to reach less attentive amnesia players and those who have not played in a while and those.
I don't get this amnesia is already popular enough thing I mean
Realisticly though I doubt FG gives that much of a [insert bad word] about it for some reason. The fact that they completely excluded CS/mod support from AAMFP( even if it divides the audience they could have just created support for both AAMFP mods and TDD CS in both games) and that they were this late with even starting to get out AAMFP assets support for TDD shows that they arent really interested in focussing too much on expanding in the community and modding area.
If it had to be done though they would certainly need to hire someone to focus on managing this though cause otherwise SOMA would be delayed T.T
