Kingdom Come's combat, for all its supposed accuracy, is going to end up even less realistic than warband's. They're taking a combat style meant for unarmored, 1v1 combat and applying it to battles featuring 30 armored combatants. They've shown gameplay footage of these battles, and they look and play like **** because of this. The ai pairs up, doing 30 1v1 duels. Then as soon as the first guy falls, one of the duels turns into a 2v1 and it just snowballs from there.
And because of the armor, the 1v1s are going to be boring, since your blows will just bounce off half the time.
And then the story will also be boring, because apparently that's more "realistic" too. Farm boy's family dies, so he goes off to fight in war, becomes hero? Never heard that one before
The funny thing is, it isn't actually a bad combat system. They just need to apply it to a setting where it actually works, like medieval street gangs, or medieval pirates. Ironically, both of those would make more interesting stories too.
