All I can say is that probably G40 and 1942.2 are mostly on OOB rules and strategy but Houserule is a kind of sinkhole in which any related topic to a given forum is lost unless Forum title is at least inside the thread Title.
Any generic original nickname makes the thread much more difficult to be related to something more specific to a given game.
Submarine, for instance, doesn’t work same in 1914, G40, 1942.2, earlier game, etc.
Any closely related like a bid or balance talk is not about other games.
It is not easy to find better classification. But Google search cannot always help find all closely related topics.
If anyone has an idea to solve this issue, it is welcome.
Sometimes, auto-censorship (even if there is an urge to talk and tell our idea) seems the only way prevent a thread from opening pandora’s house rule box.
