As someone who has only listened to RoosterTeeth podcast long enough to just barely discern the voices of its hosts and guests, but someone who felt completely gut-punched over Ryan Davis less than two years ago, I can't offer sincere-enough condolences to his fans, friends, and family. To pass in such a way seems terrifying (and, frankly, is kind of a personal fear of mine - the whole surgery complication kind of stuff) and I can't even fathom what losing someone close to you out of the blue like that must be.
No matter what your personal views were, 2014 was generally an awful year in gaming. For different reasons, 2015 is shaping up to be much the same. I hope we all keep each other in mind for the rest of the year in dealing with one another and those we read, watch, listen to online.
