>>74557105The "safest" thing to start with is either Hololive or the large indies. (I'm still shilling Dokibird.) Hololive is effectively the king of the industry right now, and their largest competitor, Nijisanji is kind of in the middle of a major scandal that's likely going to kill their overseas expansions, and by extension their english branch. Hololive tends to be relatively drama free due to proper management, but it can get a bit impersonal due to the gigantic fanbase. Gura's fun, but she tends to not stream very frequently due to health issues or whatever, so it's recommended to find someone else if you want a consistent source of entertainment. (Like Dokibird, who uploads/streams almost daily)
In Hololive, the current biggest "gamer" is Koseki Bijou, followed by Ceres Fauna and Nanashi Mumei. Bijou's probably the closest parallel to Gura if all you care about is video games. She does long grinds at video games and is pretty good at them, on top of streaming frequently. The other two are less common but have their own personalities that people tend to like (Ceres being a "comfy" streamer that you can use as background noise, and Mumei being a "surprising" streamer who tends to do random autistic shit, like drawing a hyper realistic bloody skull for no fucking reason in a game just because she can.)
Still gonna shill Dokibird, though.
