A couple of my favorite streamers are Trihex and Carlsagen42. Trihex streams a variety of games, but hes most famous for streaming Yoshis Island and currently Mario Odyssey. Carl streams Yoshis Island, too. But mostly he streams Super Mario Maker.
He sometimes plays games, but mostly goofs off on the internet. But I also like EtikaWorldNetwork. Hes infamous for having the best reaction memes for game trailers!
Mario is always good to watch as are the varieties. Haven't seen them but that is a lot different to the usual games you see streamed.
