Well he did say on stream that "he thinks he's going to have to play SOMA this halloween" (paraphrased), and I think he genuinely meant it. Its just his obsession with Blizzard games that is preventing all of us from having this wonderful halloween experience lol.
Maybe I should get a twitter account and send him a message reminding him how much we love his Halloween playthroughs. Alas I have a ridiculous workload to work through all that stuff. Oh well
