Perhaps the simplest way to implement a way for forum discussion to be closer tied to individual projects, would be to allow forum messages to be tagged with a project. Then, one can query the forum for messages related to specific projects, and the project pages could provide link to such a query.
Of course, that is easier said than done. The Game library runs on custom code, and it is possible to query the database. But, the forum runs on Discourse platform, and it is not straight forwardly easy to see how that platform can query the Game library database - it may be possible, or it may be difficult to implement.
