FYI - The fast unlock method utilizing the "close software" and reset option after playing for about 10 minutes initially worked great in the beginning. But it was eventually like the game got wise to me "cheating the system" so to speak, and after unlocking about half of the characters, it would only unlock about 2 or 3 in a row before having to manually log another 10 minutes. I'm totally cool with that because this game is just so much dang fun to play, and even unlocking the characters slowly is an enjoyable experience. But I just thought I would note for those wanting to unlock the characters as quickly as possible that for me, at least, this method didn't work perfectly from beginning to end. So there were some hiccups along the way, but in the end, I think it's still the fastest method currently known.
