For me personally, there's no reason to watch him play non-fighting games anymore. Not that those rage/dumbass moments aren't good salty fun, but those are fewer and far between nowadays. Reason being he's doing everything he can (preparation, getting help before playing, etc.) to not fuel the TIHYDP that inevitably come out and chronicle his failings. His overweening pride is shooting himself in the foot here because most people, as he's previously acknowledged, want to watch him fail and rage and fail even worse.
That's why I think fighting games are where you still get that salty buttery goodness, because once he eventually gets to online play there's no script, no walkthrough to follow. He does well for a few matches, then once he hits his skill ceiling he'll start getting bodied and the salt will flow. And it's not fake baby rage like you got in Sonic '06, you can tell when he gets really upset because his combination of FGC lingo and lag complaints will fall together in a jumbled word salad. My favorite example would be back in Ultra Street Fighter IV, his Balrog kept getting stuffed and he was gettting so upset that he was starting to combine words, I think the quote was "DUDE I can't do anything DUDE WHAT THE FUCK I'm DUZZY again" He was getting so worked up that he actually combined "that's it I'm done" with "now I'm dizzy again!"
TL;DR Philberto needs to stop worrying and love the atomic salt bomb
