The main reason why I post on this forum to to make sure my opinions are visible to the devs, should they care to look.
I lurked here for a long time during the kickstarter, keeping tabs on progress & bought the game shortly after release. I registered to get rid of an irritating sticky message, only for it to be replaced with an even longer one about being a restricted new user, so I started posting to get rid of that.
I like this game, I liked the game I bought (1.0) and after a while started to realise the Devs weren't entirely following a plan but seemed to be making changes based on community feedback that made some bits of the game that I liked worse for me. So I joined in the debates & try to state a good case for why whatever I like about a thing should remain, or should change in a way that I think might be good for the game & playerbase overall.
I tended not to post when someone had already written something similar to what I would have written, but since the sticky was added to the suggestions section about rep not being visible to the Devs I now post a lot more simply to state that I agree with a particular view.
Because of this it means that when I do post I'm pretty well always taking a minority view, but the game design isn't (usually) shaped by a show of hands. If the community has any effect it's usually through well expressed ideas and challenging preconceptions.
