Is it worth combining everything into one (the example with tournaments for different parts of Heroes applies here too)?
By the way, are they even needed by anyone? Does anyone still browse them? I doubt it, although I don't really want to delete them completely; they might be useful somewhere.
In my opinion, each of these games (the familiar Mafia, psychological Mafia, other forum game) requires its own sub-section, at least because of the presence of main non-game topics (such as general discussions, a workshop, statistics, the schedule of games, etc.).
But the same people will play all these games, and their number is quite limited. And it's unlikely that we will ever have three games running simultaneously. Therefore, I don't see any obstacles to creating a single workshop, a single table of upcoming games, and single discussion threads. In the same thread with the table in the first post, you can store links to individual very important messages that serve as instructions for the games.
And statistics... is it even kept? I once spent a long time reviewing about fifteen Mafia games and creating a table because of the unstructured nature of the first games and the lack of complete logs. Then, in my logs, I would collect statistics for the past game at the end (Arandor also liked these simplified notations "+1 to kills, +1 to defense"). And I encouraged others to do the same, but it was somehow sluggish and ineffective, and then it faded away.
