Marc and I have decided to put HotT and DBMM into the blender and see what comes out. We have played a little of each and like the fantasy trappings of HotT but like the extra detail DBMM allows in terms of movement and complexity as well as the removal of geometric kill problems.
I think really Marc just wants Goblins(S) to put on the board. We'll keep you posted here.
It looks like HotT and DBA will have new editions later this year. So DBMP goes on the back burner for now. It's more fun to play than reinvent the wheel.
