And what if, like on these forums, the players forming the council cannot agree about what they want? How many different versions of the game should Funcom make?
History shows that Funcom takes at least some of their development ideas from these very forums. Many, many nerfs are direct results of players whining about a feature being OP. On a positive side, we got things like horses because players kept asking for them.
And players, like all people, are mainly motivated by four factors: greed, laziness, selfishness and stupidity. It would take quite a lot of effort to find a reasonable number of players who can approach game development from an objective enough position to give good council, rather than promote their own favorite playstyle.
(Me, I’m motivated by laziness and greed, which is why I don’t want to work in game development, especially without pay.)
