Why ffg don't create modular board for Runebound 3 ?

By kowal85, in Runebound

I have always wondered why ffg did not make a modular board for Runebound. It creates so many possibilities of expansions that the head is small. And if it is already (if there will be) an add-on which will add a new board to the stand board and will play on a completely new area. And so you could add a map with 5-6 tiles and play even better.
