I was doing some "R&D" and found this odd game, that seems to be a solo dev Mount and Blade wannabe, and I must say it works. I haven't play much (1h), but the game combines the battles of Mount and Blade with a simplified strategic layer that is a bit simpler than the one in Shogun Total War 1.
You have 3 building slots and 3/4 troop slots per settlement. You can move troops between your settlements and attack a nearby enemy settlement afterwards, and that's about it.
It doesn't have the RPG aspects of MnB, but the combination of strategic layer and first person combat works pretty well, but I don't know how well it holds up late game (as there is much less variety in troops than in MnB, and no character skills to grind). A funny thing compared to MnB is that you don't have HuD icons to help you avoid trampling your own militia.
It is still in EA(since december 2022).
