I've just backed a KS for Myth: Dark Frontier https://www.kickstarter.com/projects/megacongames/myth-dark-frontier/description
ive got some of this firms other games and theyre prettygood, this isnt really in the HQ vein its more of a tower defense resource manament thing.
However, scroll down to the add ons section and you can see they have some faction bundles, currently orcs, tailless (ratmen) and undead with hopefully more to be unlocked soon too. These are very high quality mini's and more importanly, its $30 for 20 of the minion type models (same size as HQ orcs) 4 captains and a commander (a little taller than HQ heroes) plus the boss - which is bloody massive. from the captains up, you know your fighting something a bit tougher than normal and the bosses are a glorious sight on a game board!
i think theyre pretty good value and personally id use them with HQ quite happily! have a look and you can still 'back' the KS and only pledge enough to get the Add-ons if thats all you want.
