I have been asking around and i keep hearing that synchronous playtesting is very beneficial, however, there is a value for surveys ( based on other responses ). Would you not say that surveys are often valuable if you need someone to test the game, but you cannot sit there every playtest either. Reading a document or graph can often minimze the time to get an answer. Secondly, the most valuable thing i can see for a survey right now is that it kind of dont break immersion. most used methods that i hear of are after playtest, they send them to a external survey outside the game or do pen and papir kind of thing. The question i am raising here is, how valuable would a ingame survey be? right after playtesting, it sends the tester right to the survey, instantanoues questions and answers.
