Battle Brothers, Is a turn based tactical RPG with deep combat mechanics. Not for the faint hearted as you will lose a lot of men In all you´re playthroughs, but really worth the time Invested. I am sure a lot of you already know about BB, a bit like X-Com but historical and deeper. BTW, It´s still being updated although It came out In 2017, and has three available DLC´s.
It´s on sale at GOG and Humble Bundle at 50% off.
A very helpful series If you want to learn BB...
