So, if there was an add-on for the Rising Sun BASE game, which has been hard to find, this deal would have gotten interesting to me. Has MD done add-ons for other drops, because I have never seen them in board games. I'd say it would be an excellent way to serve both sides of the community - those who have it already and those who'd like to have it. The biggest difficulty has been making a deal large enough that MD can make money while the users get a reasonably good deal. Add-ons might be one way to accommodate a larger audience.
