Inspire me with your Reddit apps. I've got two, both game-adjacent managing stuff around the game. The first probably should get taken over by the game makers themselves but I suspect they're enjoying the free labour, the other is for a subset of players and the community we've built.
For a game community, a tiny companion that keeps the current event schedule and answers to repeat questions in one place could be genuinely useful, with mods choosing what gets surfaced. I’d keep it to one chore and make it easy to turn off, otherwise it can quickly feel like another bot filling the feed.
With games with high player churn, that's a good idea. Reddit has introduced the idea of a wiki, but the navigation into the wiki sucks, and the CMS aspects aren't great either. We have a tips and tricks page in the wiki but it doesn't really work well.
