didn't you just see Miko's sololive a few hours ago?
the idol appeal is a huge part of it.
If gameplay was what I or what most of the jp audience wanted then the fps and kakuge tantou holos would have better numbers than the variety holos but they don't, and really they'd not watch Hololive in the first place if they wanted that content anyway. There's tons of options to choose from between the nico roujins on twitch, kronoir from niji, the entirety of VSPO, etc.
It's also why perms are just cope, especially when holorisu could enjoy a holo dig a hole in minecraft for three hours
