So, what's good?
Currently I'm working on second campaign, looks very promising. To level up the combat, I'm making 3d-printed FDM flat miniatures. They still need some work, and I'm yet to figure out how I'm gonna paint them, but yeah, they look kinda like this (only Republic's basic units are ready rn):

Kinda tried to paint them with colored pens - honestly, looks like I'm gonna stick to these guns, haha.

The one main takeaway from the first campaign - since we don't have hex field with big hexes, had to homerule scales and distances. Basically, I've divided "bix hexes" to smaller ones, turning those into "areas". This way this ruler was born, gotta place it's end on mini's head and then check in which area possible target fits. Having several of these during play helps with the combat a lot, allowing players to measure distances and test LOS of their Frames right on spot.

I also made a whole bunch of basic terrain and obstacles - rocks, buildings, fire tokens, turrets, etc., but those need rework, especially since I'm going for that "flat" oldschool look.
Later in January I think I'm gonna try and make several digital maps, for VTT and using with portable projector. We'll see how it goes. Meanwhile, if this looks promising - leave a reply or something, and we'll figure out where should I upload these .stl
