Oh, my favorite streamer is RTGame! I used to put his stream plays in background while I do some work. I've binge-watched his entire Hitman, Ace Attorney, and DBH gameplays
He's a natural comedian/entertainer, he doesn't need to overreact or scream at the mic to be funny. I found him through his Cities: Skyline highlights on Youtube. (Tangent, but because of that I bought Cities: Skylines for my boyfriend bc I thought he'd like it and I was right, he absolutely loved it. Around 400 hours of gameplay, haha.)
Another streamer is Tuonto, I've never caught his streams but I do religiously watch his highlights on YouTube. One of my favorite Genshin players, but I love that he also diversified into other games like horror games. His screaming in horror games makes me less scared LOL.
MoistCr1tikal (penguinz0) is also a streamer I follow, but mainly for his highlights and commentaries. I wouldn't recommend him to a younger audience because he sometimes likes bringing up mature jokes, but otherwise I love how he comments on everything. I live for the drama he covers LMAO.
