OK guys. So, here's the current brainstorm for 1/72nd armies/units plan:
Combined armies of the free people's of middle earth:
13th century knights = guards of the citadel
13th century knights with teutonic headswap and possible greenstuff capes = fountain court guard
Medievals with spears, swords, bows = warriors of Gondor
Scots = axemen of lossanarch
German cav = Rohan
Russian knights = Rohan kings household
El Cid Iberians = something Gondor
Combined forces of the dark Lord sauron
Dunlendings = alliance Cimmerians
Orcs and uruk hai = alliance sets
Armored trolls = alliance sets
Arabs = haradrim
Armored Muslim warriors = easterlings
General fantasy:
Republican Romans = basilean counts as, with God's and mythical creatures Elohi, etc
Cimmerians with a different paint scheme = varangur
Arcane legions stuff:
Romans = abyssal dwarves/frozen north scheme
Egyptians = undead, not empires of dust. This is because I'll mix in Caesar skeletons
Han = elves/ terracotta army
I've got ideas if a cross between alliance Amazon's and historical Greeks as trident realms with a blue skin paint scheme.
