Actually I am looking forward to see this marriage thing.
Personally I would prefer some settlement foundation update, so you can grow your own village. Hire people from other settlements and maybe the join your village when dont need their direct service anymore.
Some things I would also like to see is, growing your own animals, speak if have a sheep and a ram, there should be a chance every year to get an young sheep/ram.
Getting wool from sheep would be nice aswell.
More craftable basic things in vanilla, without needing to mod the game, is also a thing I really want.
Some easy things like nets, fishing rods, wooden tubs, pot aso. -- anoying that we can get those things only from trades.
Overwork of arrow crafting also needed, stupid to make arrows just from a branch, rock and feathers without any quality. Arrows should be made from shafts, arrowheads and feathers.
Some use for bones beside feeding dogs.
And a tailoring proffession, really missing.
Abillity to tailor nettle and woolen clothes and option to repair it if damaged.
There is so much potential in this game.
Well lets see what will come in future.
