I have a few things that i would like to see with only about 100+ hours in and reading some great ideas
there are always changes that can be made to dialogue and the like.
I'm sure the devs (or dev) will come up with some amazing new characters and adventures maybe linked to the "war"
here are a few ideas
I think legendary fish should be able to be caught multiple times per save but only one per in game year of each species, or they should be able to be raised in ponds one pond per year per species and it takes a year to gain one fish in the pond and it has a multi item requirement.
Maybe another skill or skill tree:
hunting- for deer, bear, rabbit, turkey mystery/rare animals and have either petting zoo or zoo buildings, or animal products like furs and meats. have tier skills that raise values or trap efficiency percentages.
artists- use items to create sculpture, paintings, pottery etc as part of grange display or new event and have a collection of art with values to different materials level skills to raise values and gain new abilities.
Maybe some more crafting for machines, working with Maru and Robin and even Clint to build machines or devices for your farm that do multiple things (maybe craft your own mower/tractor to use or even race
) or to expand train and mine cars with quests and item requirements for new machines
go as far as map expansions or new dimension maybe from the witchs swamp to another world with more mystical or fantastical creatures
just a few ideas
