How about creating a separate “Feedback” topic under “Forum” where players can report their experiences with new content? Game designers and administrators could also leave requests for feedback on specific content. Not all feedback is associated with a suggestion for improvement.
For example, I just discovered an above-ground ruin for the first time in what is most likely an undiscovered area, and would like to know if this content is completely new or extremely rare. Or if I just somehow managed to avoid these ruins until now.
I would also like to know if these ruins are part of a mod or if they were developed specifically for MeseCraft. Background information is sometimes useful for specific feedback.
I think I might have seen ruins of this kind somewhere before. If so, it was so long ago that I can’t even tell if it was in a single player game or on a server.
