I created the Game_Rules wiki page a few weeks ago. I see that you can't search for just "rules" or even "game rules" to find it. Is there a way to format the page title so that the space doesn't get replaced by an underscore? I suspect this is what is killing the search.
It's been answered on that page. It serves as a sort of "feed" for all new game rules. If you are looking for specific rules, you would of course go to that game's page. But if, like me, you are interested in ANY new game rules that come out, you can watch this single page for all updates.
