What if we could make our own music like the game music by using instruments? Like that you can make your own songs, maybe even make a band with your friends, give it a nice bonus if you play together in a party. Wouldn't it be great if you could travel around making music? Could maybe be linked with feasting to make you more happy/decrease travel weariness? Or maybe that you can fill a gauge for the symbel to honor the ancestors and get numen points or other stuff, with random gifts on an altar or table, or whatever you can come up with.
Make like 10 diffrent tunes for each instrument which you can put together to get a tune, write it down on hide/paper with inkweed and being able to put it on a stand and play it when you want/can/have to.
Make 2 diffrent types of instruments, 1 including only food and strings, for the new players or non-metal access ones. And 1 including metal (Strings, stands, fills the gauge faster?)
Just come to think of it, to make it easier after you make a proper song you can save it in your instrument or on paper, just load up the paper at the stand and play with your friends and have fun. Just imagine how cool it would be to have a large open place with people feasting while others play. Hell even make Wardrums to increase damage and strength

Besides that what if we could make a townhall for the village? A large hall which can only like the chieftain select to build in his screen, and ability to make it large a massive large feast room. Perhaps even a capability to lock so that you can hide in it during a raid (Ofc you can make a skill to picklock it or smash it down) just to give the game a more "fun" feeling. Hell I would fill a wagon and go and play for people just for teh lulz.
