Nothing big in 6 months? Are you even talking about Bannerlord? I mean they fixed a big number of bugs, added new armor sets for Battania and Sturgia. Added late game horse harnesses, improved ai diplomacy, multiple new quests, added cheering, added multiple perks, added multiple females to avoid clan destruction, with hooked spears you can take off people, they added modding tools and much more. If that's not enough for you, then I am very confident that with even their biggest update or full release you still would be unhappy.
