There are a variety of ways to accomplish things in Discourse.
For example Tags can be used in a category to organize topics. As mentioned Subcategories can also be quite handy.
Ie
In the Above model
Game1
Main area use Tags for game play/content(not sure nature of gaming)
Subcategory
- Rules & Faq Wiki. (Game staff group)
- Game1 Help - Special Category for questions
If Self hosted plugins like Solved can be used in the Help Category. Have topics here always start on first post. Op can mark a reply as the solution which uses a special quote in first post…so use category setting to always default to first post when a topic is viewed.
