Sorry, I had a thing written up and the bug ate it, so I was giving it some time to "settle".
Here's the brief version though:
The aim of the system from a mechanical perspective is to be relatively simple, using conventional mechanics with a few twists (d10 rolls + modest modifiers).
The purpose of using rather simple rules is to enable what I like to call "big skirmishes":
Battles between warbands of 30-40 individually based figures on each side.
A lot of things factor into making this possible: Straight-forward mechanics, a lack of tracking as much as possible (off the top of my head, only two things need markers, units that have been Rattled (failed a morale check) and damage to monsters which is tracked by a single D10 placed next to them).
This way, you could have a few monsters, heroes and several "squads" on the table.
As more options are added, you'll also be able to construct your own troops and keep them around across battles, though the experience rule is intentionally very very simple, though quite effective.
The game is also going to receive a fairly steady stream of ongoing support, consisting both of paid mini-expansions as well as free additions, which will add to the number of units available and the number of options and battle conditions you can apply.
I'll do a post on the mechanics tomorrow night if all goes well.
