I just got an email about this open beta from AMD, it sounds like it could be cool. You can install the open beta from here: Steam :: Ancestors Legacy :: Open Beta, Pre-Order and Release Date Revealed!
Ancestors Legacy is a historically accurate real-time strategy game influenced by historical events in the Middle Ages. The game combines resource management and base building with large-scale, squad-based battles across vast battlefields, all rendered in great detail thanks to the Unreal Engine 4 tech. Experience medieval bloodshed like never before, thanks to the cinematic action camera that puts you right in the middle of the battle at the press of a button.
