Fish strikes me as person who might me manic depressive. I remember in Indie Game The Movie he was asked at some point something along the lines of what would happen if he didn't finish Fez and he said he'd kill himself like completely non-jokingly. He seems to be one of those guys that has become a victim of his own success. By all accounts, the development of Fez was a nightmare and took a toll on him. I can't imagine the idea of making Fez 2 sounds like a fun idea for him. He went from just a regular dude one day to some indie darling overnight. I imagine it's hard to go from a regular person to being instantly kind of famous in the indie game scene overnight and all the baggage that goes along with it. That being said, he really does seem like a guy that takes criticism really, really hard, which is why I wouldn't be surprised if he's manic or has bi-polar or something. My opinion of the guy is that you might not like his personality or some of the things he's said, but we should judge him by the games he makes not his personality. I feel like sometimes we attribute traits to these people that we have never met and that narrative sort of becomes fact on the internet like when people call Fish an asshole or Blow a pretentious hipster. In all fairness they might be, but I've never met them in real life.
