And why did you stop watching them?
MatthiasGaming: I felt like when he got bigger his personality changed, it almost became like a show/fake persona.
Arumba: Became a cranky unhappy person unfortunately…
A fewl (I don’t want to give a platform): Became angry biggots:X
Jesse Cox/Pewdie Pie/Markiplier: outgrew the sense of humor/entertainment.
TLDR: Usually some change in personality alienated me.
In terms of the gaming ones you listed I only watched markiplier. Specifically the FNAF stuff. That was a lot of fun almost 10 years ago when it was novel and new. But now the genre is so played out and the whole “scariest game scream at the camera” thing, while maybe based on something genuine then, became obviously forced and annoying after not that long.
