you can see it that way and i understand your point of view i guess, but its not really wasting time. feedback actually helps a lot and keeping contact with customer/consumer comes quite in-handy in software developing, it will actually bring a better experience for us players on release the more we test. anyway, playing a game is all about having fun and i think it would still be fun to play despite a wipe later on, but hey i can totally understand that if you like the feeling of progress
