Well, the line is there because at some point, you wonder if there's a need for a board at all.

I think the neatness of board games is also in having some level of self-contained mechanics. A companion app to help keep track of stuff, or add some value (ie music or narration) is neat, but this was like, more than half of the mechanics in the app. The map tiles weren't even needed, as were the location tokens and frankly, the really neat minatures. It was just a few steps from being a completely digital game.
