Most if not all devs on the itch forums are not going to posses skills needed for such a project. Things such as dedicated servers, networking, and deep systems that can be scaled are just not a thing relevant to most games that people release on itch. I would suggest searching for professional developers, which as far as I understand, don't look for work on the itch forums. Also what is this project? The paragraph long description just makes me more confused as I try to imagine what kind of game this is.
Ahh makes sense, fair enough.
I guess a more fitting term for the genre is probably science-fantasy, like the StarWars, Dune, Warhammer40k and other similar franchises blending fantasy, sci-fi, dystopia, cosmic/horror and more into one giant universe/franchise.
Our studio website is currently in the making which will contain all informations and details about the whole Marshland-Project and the associated games within the Marshlandverse.
I will make another post in near future again, adding the link of the studio website so people can check out all details, because its way to much content for a single forum post.
