As a beta tester i can say i am very happy with Legend Keeper so far.
I love to gather Visuals when i am creating settings. and to store them on a map and give them wiki pages and so on totally works for me and my kind of workflow.
Together with wonderdraft (wich i bought a week ago) and some 2minute Tabletop stuff i punch together via gimp i am fully set to create!
Really got my juices flowing
