Pure conjecture but I think it is due to the presence of already well-established LCG's, like Netrunner, aGoT, etc.
I initially hoped that the game would draw in the 40K tabletop enthusiasts but it doesn't look like it has.
Apart from a small dedicated community to the west, the SW LCG is also DOA.
(in my own country that is, not sure about the rest of Scandinavia)
