I think a forum can still work well for gaming communities, but it probably needs to complement Discord rather than compete with it. Discord is great for quick conversations, while forums are much better for guides, FAQs, bug reports, and discussions that people might want to find months later through search.
I'm actually considering something similar for a gaming site, ''Stickwarmods'', where we publish content related to Stick War Legacy Mod APK. One thing I've noticed is that users often have detailed questions about strategies, updates, compatibility, and gameplay that are difficult to keep organized in Discord because older conversations disappear so quickly. A forum seems like a much better place for that kind of long-form discussion.
I'd also be interested to know whether anyone has had success with features like badges, solved topics, or reputation systems in NodeBB. Do those actually help encourage people to come back and participate, or is most of the engagement driven by consistently posting useful content?
