https://forms.gle/bmNEbcXVPFtnY2uR6I will answer these 2 a little just because the information is already on the thread(s).
Hows arty going to work and will sieges be top kek because they could be a rlly big pro over NW for the casual events
I will say we are intending to put some good work into forts etc. as that was a large part in napoleonic warfare, particularly during the invasion of Austria. If you take a look at the screenshot on the main thread, there's a very early fort design, maybe around 10% done but personally I think that its still better than anything we have on NW currently (outside of community maps naturally)
If the singleplayer turns out to be like L'Aigle, then I seriously cannot wait as I don't really like the multiplayer in Bannerlord.
As it says on the main part of the thread, single player will be more scenario based content. I guess a way you could look at it is the Historical Battles in Total War games like Napoleon, Shogun etc. But this won't be worked on until the Multiplayer portion is complete. Or if the Level Designers etc. do not have a lot of work left to do on the Multi.
But do try to remember like with MM for example, the multiplayer will be quite a bit different compared to base bannerlord so make sure you at least give S&M a go on release
