So does that mean I can use non-IHMN figures for IHMN games then?
Of course you can Mark. My 'non-official' schoolboys have been waiting for suitable opposition (in fact they have had to transport themselves into the 20th century for the opportunity of a (VBCW) game).
Seriously though, the rules encourage players to create 'non-official' forces.
Must sort out a game soon ...
