Maybe I wasn't clear.
I don't believe that the fans that respond to open playtesting a) necessarily represent the broad average of players, and b) I don't think those fans motivated to answer are necessarily motivated to make the game better and instead are motivated to make thegame stay the way they like it.
I think designers should be trusted to designa game.
If you are going to do a playtest, it certainly should not be piecemeal and in brief intervals. you should put out a wholly playable version of the game and let people play it as if they would the complete game, and take feedback on that.
I understand what you are saying, but honestly, I really don’t agree at all.
I’m not sure if the impetus for this thread is specifically targeted at 5.5 but as I pointed out, other very notable companies have also done playtests. I have a hard time believing that all of these designers are not deriving value from them, or that they are creating a blindspot for themselves because they are taking input from those who get involved with the playtest.
