BTW, I was inspired to boot up Jagged Alliance 2 and play it.
I noticed that in that game, enemies only drop like a magazine and rarely a whole gun.
In this game, units drop broken guns and those are at least worth like 30, and if they're like a Mini UZi, they're worth 200.
I'm also a fan of not having to constantly wonder how to get ammunition. Even on the worst days a bullet is like 5 dollars and a old pistol is worth 40 times as much. It's not worth managing the cost and supply of ammunition.
