One of Us: Seamus is aware of his TV Tropes article here. In addition to his video games, Seamus has a variety of collectible statues, numerous DVDs including Dragon Ball Z, and more (including Slurm shirts)!
Urban Legendof Zelda: Despite Seamus outright denying it several times, some people are still convinced that the "SSoH" part of his user name either stands for his real name (Seamus O'Doherty) or "Sarcastic Sense of Humor". He has even pointed out that it came from a time in his life before he was overly sarcastic.
There are certain games Seamus will never play on his channel (like The Legend of Zelda) because the fanbases of those games would rip him a new one for not playing like how they would play. Seamus already gets flak from some of his fanbase over casually playing certain games and doing things like missing a non-important safe in front of his face in The Last of Us for example.
The unpleasable fans are why Seamus rarely replies to YouTube comments anymore and some of those fans are spreading to Twitter causing new fears of Seamus ceasing posting/replying on Twitter leaving his subreddit as a last chance for fans.
