This doesn't change the fundamental problem with gameplay (which I ranted and ranted about in October) and simply like the last con-con changes the name, and legalism behind our system without actually doing anything else.
Even if we have nations, with there own leaders, and parliaments, it still won't change the fact that there's no policy simulation in the game, and that activity only seems to occur around election period. We've had this exact problem since summer '15, and we haven't fixed it.
True policy simulation would require individual players to have an income, as well as personal relationships, that they must upkeep. That would require a great deal of effort.
