Always glad to hear about 6mm fantasy. Even if I have rules that I tend to use to exclusion of others, I am very interested in hearing about other rules, as I am about figure manufacturers that I don’t have figures from.
Every so often I like to give my 6mm Hordes of the Things armies an airing. I like using double or triple sized armies for 6mm. Some of my 6mm armies are Baccus ancients armies with fantasy additions, but I have a few Baccus fantasy armies. Some of the Irregular Miniatures 6mm stuff does well, but I don’t see their line of battle troops as being compatible with Baccus. Sometimes large creatures from 10mm lines can be useful.
