Meanwhile here I am on TW Attila, cleaning up uncooperative Holy Roman vassals and Aragon, all while trying to recover from the black death and secure newly conquered territories:
I've been running this campaign for over a hundred years in-game and I'm still not anywhere close to being bored. This game, without any story or dialogue whatsoever except ones you make up in your own mind has me immersed more than I could ever Bannerlord doing in the current path it seems to be taking. Some side missions and companion stories can initially be good, but imagine progressing a campaign for centuries and you're still doing the exact same missions. It'll get boring, whereas a dynamic world such as that of 1212AD's, though imperfect in many aspects sure, won't get boring as quickly, you can always come up with better stories and lore and that keeps you going. Especially if you like worldbuilding / writing or just fantasizing, this can be a powerful incentive in fictional settings.
I could make a whole another thread comparing / making suggestions while taking inspiration from 1212 AD, but for now this part was relevant.
