This is basically my view. I think if anything would be merged it would probably be the Other Leagues being folded back into the Other Stories section, rather than mixing cricket and non-cricket stuff.Even though the other game stories has no activity, is kind of serves as a gateway to the other leagues and the mafia games, like this used to to the cricket leagues section. I just think that it makes more sense to keep the other stuff separate from the cricket stuff, but that's just me, it wouldn't really bother me if they got merged.
Though I suppose the other aspect is to think about the difference between a league and a story - I wonder how many users are put off putting effort into narrative structure when that would mean posting in a less active story section rather than the leagues one?
