Hey there,
after the stresstest - weekend and the following survey i made up my mind a little.
Wouldnt it be more effetive, to transfer this game into open beta asap, but with the following tools.
Everyone participating gets some kind of survey every hour or so. behind this survey there has to be a mechanic, that tracks all the stuff that you were doing putting together a unique survey for every player that you have to complete before being able to go on testing.
I think i have had this kind of stuf back in the days, but i dont know which game that was.
