Did you mis-refer to Bannerlord as Warbanner 2?
Well, it is pretty close to both Warband and Banner.
Chivalry is fun, but from what I've heard the competitive community has become a little ridiculous.
Mount & Blade Warband has a great single- and multiplayer, but especially the singleplayer. Here's the first result for "warband 2v2"
, seems pretty interesting, especially once the shields break. There's other more classic team game modes too, as well as Duel. Highly moddable.
Toribash is close combat and invisible skill ceiling, really cool, but hard to learn.
