theres a game which got steam greenlit and looks a bit like a m&B open world game to me. its called kenshi, it looks promising.
Kenshi looks nothing like M&B, it doesn't even have directional combat. You just click and order your character/s to attack.
Kenshi is very appealing to me, however, due to the open sandbox.
Also, M&B2, I don't know about it. Is there anyone else with really low expectations?
