4) how about ancient firearms, like a , a possible "early" version of the mortar? may be unlocked with the blaxk market, and supposed to be oitdated when gals learn to manufacture assault cannon? or even a gatling machinegun, an early black market machinegun?
Uh, the early mortar kind of required a team of horses to move, I'd estimate it at 600 lbs easily. If I'm remembering correctly, it wasn't useful for anything beyond removing a castle wall, though admittedly it was pretty good at that.
We do in fact get early access to a gatling, or something similar, it only requires an extractor to build. Though I can't remember what techs are needed to get it.
On another note: I'm pretty sure the air balls are more of an emergency weapon, for if you have to get the air game up but haven't had luck with drops. But I agree that they're not exactly designed to be useful, based on the description, they're literally large grenades thrown out the hatch. More useful if you are trying to bomb a ground target, but that's not something we generally have to do in this game. Think early WW1 air combat.
Note the third: Any attempts at a long war version? where research beyond the very basics take a while and ramping up to frequent crackdowns and mercenary or star god presence is delayed a great deal? That could allow for the crude early firearms to actually have some time in the sun before being replaced. Maybe make it harder to get enough trust to actually buy better guns, muskets and pistols seem to be replaced by revolvers almost instantly, despite the lower damage, twice the ammo per unit is just that valuable.
