Has anyone tried adapting the Warmaster rules to 28mm miniatures?
Yeah, Rick Priestly has:
I am not familiar with the Hail Caesar rules. Why do they make a better starting point?
It's basically Warmaster (Ancients) 2.0, usable with any scale but primarily 28mm.
Might be easier to plug Warmaster's magic system into that - it's already pretty free 'n' easy, and open to tweaks.
