I think this, "take said theme/setting and apply Souls formula to it", is extremely short sighted and completely missing the point. If I were From, I would do the following as an armchair CEO:
-Make exclusives for the three main consoles
--King's Field V for PS4, co-developed with Japan Studio
--Otogi 3 for Xbox One, co-developed with Microsoft Games Studio
--Lost Kingdoms 3 for Wii U/NX, co-developed with Nintendo producers, etc.
--Tenchu, cross platform, with similar online integration as the Souls titles (they still own this, right?)
Done. Portfolio instantly more interesting and diverse than what they've been doing for the past few years.
