LEGO (board) Games was successful when it first launched- like a shockingly huge success- the only issue was that it couldn't keep that momentum and it was rather quickly showing that it's potential had been fully tapped in regards to what consumers would purchase from LEGO in this regard. Aside from like a one off set like the Harry Potter chessboard I really don't think board games holds that much potential for Lego, especially as a entire theme.
