Warband was a bit of enhancement of the first MB game, it was made by a really small group of people, so that's why some features were pretty simple and not deep enough. Like it or not, but they still served the purpose.
In some areas Warband was really a simple piece of code.
Bannerlord on the other hand is in another league. Created for so many years, by so many people, with better technology and resources and the funniest part is, still don't have even those pretty basic features that previous game has. Does it ring a bell for you or still not?
With those resources, they could make this feature massively better, but they choose to scrap it entirely. And not only feasts, other things expanding the world and immersion are missing too.
Bannerlord has one thing done well. Battles and combat. And that's it.
Without mods, I'm not even touching this game. And I think that's sad. After all those years, still ordinary people from the outside are needed to fix BL.
Hilarious.
