True, as long as the world stand on its head.
I think the three most important points are ping - pop & world size.
If its big enough to be crowdy but gives room to hiding from society, and with no ping issues especially in the heat of a fight, it might be a mess but it can still be fun.
Hell, PW is orderly AND a mess : random assassinations and cool orderly officially stamped wars happens right and left, and the world is pretty small for a "MMO" + the ping can be harsh. Still one of the most successful warband mod.
