Did OP play Ark, Conan, or even Space Engineers EA? Compared to how those games were during EA, Bannerlord EA is in a decent state. yes, there are balancing issues, yes there are performance issues, but the game on the whole is fairly playable.
Ark (and Space Engineers too) EA had serious performance issues (think Bannerlord has leaky memory? Ark would straightup kill your PC). Conan's NPC AI was so bad, you could stand 2 feet in front of an enemy and they'd ignore you (and don't even mention defense thralls, they'd straight up ignore burglars looting your house).
It's EA. It is the barebones skeleton of what the game can become. Doesn't excuse everything, but it does mean we should not expect a finished and polished game. Look at how much Ark, Conan, and Space Engineers improved from the initial EA. You can't even recognize them (Although Ark in general still has unacceptable problems).
