I bought this game several months back and play it on and off as it updates and so far I am very impressed. It is an early access game but I have the utmost confidence in the developers. They have a project with a goal. Nothing too ambitious and at the same time it is not underwhelming. They take their time while working at a timely pace.

As for the game itself, Battle Brothers is a Turn Based Strategy game about managing a company of mercenaries in a high fantasy setting with bandits, goblins, orcs and even zombies (among other things). It has a leveling system that works by character as well as a permadeath system. You gain loot, exp, and gold from completeing missions or clearing out enemy bases that randomly spawn on a radomly generated map. As you complete missions you gain reputation with the various factions generated with the map. If you fail missions you lose reputation.

The interface: It is clear and easy to grasp, the game is so simple to get into it barely needs a tutorial. Buttons are clearly labeled and inventory management has a sorting option, making it a breeze to go through your stash.

The combat: The combat is almost like a mix between your standard TBS game and chess. There really aren't many animations and the characters are 2D game pieces. It has various weapons and fighting styles as well as skills that characters gain as they level up. So far it is balanced but not equal in that there is balance, but each enemy has a different fighting style that you have to adapt to. It can take a lot of trial and error if you don't read a guide (which I do not personally consider a bad thing)

The AI: I am actually very impressed with the AI. Human enemies are fairly unpredictable, goblins are sneaky opportunists, while orcs use brute force and shock and awe. It puts you on the spot to choose a fighting style and formation to fit the type of enemy.

Graphics: They are on the low side. If 2D characters over a hex background are a dealbreaker for you, this game may not tickle your fancy the way it did for me and many others. They are smooth and demand very little however. Most up to date computers should be able to run this game with no problems. While it is 2D I actually enjoy the art style used for characters and weapons.

Cons: My only real gripes are the lack of story, lack of depth in the faction system, and repetitiveness. While I have a lot of fun with this game, it is easy to slip into a grind where you are running missions just to replace the men and equipment you lost on the previous mission.

EDIT: Review update for Feb 25, 2022
The one complaint I had is no longer relevant. It has multiple stories that tie into endgame crises'. The faction relation system is also deeper. They have a handful of paid DLCs that add more than their value to the game. What really seals it for me is the free DLCs. There is a big free DLC coming March of 2022. The devs are so passionate about this game and they do everything they can to make it a game they would enjoy. I legit cannot recommend this enough. If I wasn't so broke (thank you Steamdeck) I would buy this game 10 times over to give to friends.
