The channels
The standard stack: a group on the platform (the in-platform home), a Discord server (the real community hub — announcements, feedback channels, support), and social accounts for milestones. Start small: one announcement channel, one feedback channel, one general chat with basic rules. Empty channels look worse than no channels.
Feedback triage
Community feedback arrives as noise and leaves as signal if you triage: bugs (track and fix), balance complaints (watch the data before acting), feature requests (collect, count, prioritize), and noise (acknowledge and move on). The public habit matters most: responding visibly to a few pieces of feedback teaches the community that speaking up works — and that you are the developer, not a support robot.
Rules and the trust loop
Write five rules, pin them, enforce them evenly — especially against friends and top donors, whose violations set the real tone. The trust loop compounds: developers who ship community-requested features get communities that defend the game during bugs and outrages. That loyalty is marketing you cannot buy.
