Looks like a great battlefield!
What do you like about Warlords of Erehwon? I remember hearing about it a while back (5-10 years?) but don't know anything about how the system works.
It's built on the same engine as Bolt Action and Beyond the Gates of Antares, if you know either.
Here's a short breakdown:
Easy and flexible unit building.
Infantry units start with five models but can be reinforced up to ten. Cavalry typical 3/5. This is a very nice 'hobbyist' approach, because as soon as you have a unit on the table, you'll be able to use every model of that type you'll ever paint.
Random order of activation.
For each unit you put a coloured Order Die (some monsters add more than one) into a bag, those are shuffled, and each turn dice are drawn one at a time, the colour deciding which side can activate a unit.
Multiple order options.
Each order die has six different orders on them, the order you choose decides what the unit can (and cannot do) this turn.
Suppression/morale/fatigue, here called 'pins'.
Play a BIG role in the game, units rout or get destroyed if they don't manage their 'pins'.
Easy and simple rules for shooting and HtH combat.
Clear victory conditions (in a simple head-on fight the winner is the one who destroyed half of the enemy units or killed most points).
And, of course Priestly's sharing of the points system. It makes it very easy to invent new unit types, or adjust existing ones.
I am doing my own version of the Grimdark universe, where I make profiles for 'Warlords of the 41st Millennium'
