interaction other than just fish

Have just finshed the EA of Sub2. I liked it a lot, but very similar to sub1 where the story involves a lot of exploring aimlessly until you happen upon something of interest. Although as the story suggests the axum are no more, what if there was a surviving tribe that you could gain the trust of and then interact with, and do something similar with the tailings… it could still follow the lore but the interaction would make the experience a lot more interactive.
