If you want to see a Ark Survival Evolved forum, just comment I do or give a reason to have a Ark forum, it's a popular game and I would love to see people getting together to help make servers, or to just play together
It sounds reasonable and I'm surprised there isn't one already? I don't own the game but I think it'd be a valuable resource to plan ahead. With them Emgrams as such.
I think there should be a section for all types of "survival games" such as dayz standalone, h1z1, ark survival etc. That way, it would bring traffic from all three+ games as well as not fill up the home page with a bunch of smaller indie games.
If you want a forum for it make more activity about it. While it seems like a fun game, it has a lot of work to be done on it for it to work well and I think that is why people aren't as interested in it.
