My name is Nico aka Knakveey. As you've probably noticed, this community has really taken off along with the success of the game. I wanted to reach out to offer some suggestions and extend a helping hand.
The mainpage is a bit basic. Perhaps changing some of the formatting, moving up the categories, and some other additions to the right rail could make the community more invited.
The overall theme of the wiki could perhaps use some love? Adding a custom background and wordmark can do wonders.
What do you think about these changes? I can show you some "mock" editions on my sandbox (private wiki) if you like. Or if you need help with anything, please feel free to reach out to me!
The status of the wiki is not yet clear. See this discussion.
I understand what you're saying. Having a better skin and some "love" would indeed help the Wikia page. But it seems to be a losing battle, as the developers and the community have started moving to gamepedia.
I could make a list of pros and cons for the two competing wikis, but, again, it feels pointless.
Besides all this, my interests were more surgical: automate some tasks, have some fun learning to wiki. My time is quite limited and I couldn't envolve myself more than I already did. Sorry I can't help with the tweaks you mentioned.
