RP posts, mafia games, forum games and the like are deemed by the general ZD populace to be "not constructive to the forum", and as such were not granted the title of "real post". Its been an on-and-off debate on the site for years, despite their positive community-building aspects. People just don't want ZD to turn into a forum that's focused on RPs/mafia/games/etc and completely drop the Zelda aspect.
While I feel like all that is a decent chunk of our community, and what has really kept me on the forum while Zelda interest was waning, I get the arguments too and dont make a huge fuss about it.
