Battle Brothers is a very good little independent game that puts you in the shoes of a captain of a mercenary company in an era that resembles our Middle Ages. The graphics are certainly sketchy but very convincing, much more than you might think.
This is a turn-based tactical and strategic type of game.
Your goal is not to defeat a country but to rent your mercenary companies to the highest bidder or even earn some money with trade.
Each game is unique in itself and don't worry you will die and you will still get joy to found another company.
It's a very addictive game that I highly recommend to lovers of turn-based tactical games.
