Avid video games critic and YouTube personality John “Totalbiscuit” Bain has passed away yesterday after a 4-year long battle with cancer. Bain's wife, Genna Bain, has posted his passing on Twitter, and many of Bain's fans and game developers all over the world are paying their respects for the much-loved game critic on Twitter and on YouTube.

Bain grew to prominence for his matter-of-fact reviewing style and the exposure he gave to lesser-known games. Titles like Warframe and Path of Exile reportedly found new followings thanks to Totalbiscuit videos covering their early beginnings. Bain also delivered scathing takedowns of loot box-based business models and proved that games criticism could come in many different forms.

In 2014, Bain was diagnosed with bowel cancer. Bain went into remission though, but the cancer returned last year and spread to his liver and spine. At the beginning of this month, Bain announced that he would be retiring from games criticism as his liver is failing, but that he plans to continue streaming and making YouTube videos in the form of co-op gameplay with his wife, Genna, in hopes that she would take over his YouTube channel when he is gone.

Bain confidently said that “I fully expect The Co-optional Podcast to go on and I love the thought that once I’m gone, the channels will go on in my absence, hosted by the person who knows me best and has been with me for the better part of my adult life.”

Genna Bain has posted a heartfelt message on Twitter, and she mentions in a reply to Fortnite's official Twitter page that "During the hepatic coma he was slipping into several hours before passing, TB was still reviewing and talking about [Fortnite] in his sleep," doing what he loved most up until the end.

Thousands of fans are sending messages of thanks to Bain for his invaluable contribution to video games and video game criticism. Bain has been described by fans as "a dedicated and honest gaming critic," as "a true hero...who really cared about honesty, integrity, devotion and a truly amazing man," and as "a hell of a funny guy." Bain's insights and opinions about video games will be sorely missed, and the video game industry is certainly poorer without him around anymore.
