I've played about 15 custom stories, but don't recognize any names...sadly.
I'm gonna try out the editor and planning to create one sooner or later, depends on several things.
I love The Great Work, so I think Damascus is a great modder, I also loved Obscurity by ElectricRed, I'm currently playing PEIRAPRIGOND, and it's awesome so I think Landvaettr is awesome mod maker, Endosine for making In Her Memory (it's not yet released, allthrough I know I will love this mod), Damnnohtml for making TTP, xAmn for Down The Rabbit Hole and of course DeAngelo for making awesome and unique A Late Night Drink.
EDIT: Forgott about Acies, Library for Alexandria is awesome
I think these guys really should get a cookie from me.
