I hope there will be a lot more to do with the town/village/lords quests-jobs instead of only a few selection.
Additionally, something that really annoyed me with Warband native is the companions, they all have a background story they're telling you at some points of the map , and what they tell you hints at there's something to do, something to be done, etc...
But there's in fact nothing, it's like the devs planned companions specific quests, left the texts in, but actually scrapped the quests/missions related to those.
I sincerely hope the companions in M&B2 will then be more worked on instead of just being "permanent" canon fodder, there was a lot of potential with them in Warband that never followed up.
Same with the town people that you can interact with, in Warband those interactions are very limited, making walking in town/village nearly useless as after a time you'll only use the town/village menu instead of actually walking in.
I hope they will make the player feel a bit more uninvolved in the campaign "story" too, that's probably why Light&Darkness is my favorite Warband mod, as it involves you a lot more in the events unfolding than just a text or two popping up, while keeping the battle-siege gameplay of Warband intact.
The visual upgrade, i don't care honestly, i always made the choice to move to DX7 display in order to have larger battlesize without the performance issues, and enjoy it like this anyways, so more poly here or there, not what i'm looking for.
