She mentioned that there's maybe too much Bethesda on her channel yesterday. Obviously you can read that as just wanting to be done with Morrowind (fair), but it's interesting to think about.
Her existing viewers would probably be very positive about that change. I mean they're constantly talking about playing other stuff. And so is she of course; BG3 and this Nuzlocke have to fit in somewhere.
But themes aren't really *for* the existing fans, as far as I can tell. They're for getting new ones, building rep etc. Then again, you can argue that almost any gimmick is bound to be outgrown as a channel gets bigger. You see that all over youtube, not just vtubers. So it's more a matter of "when" not "if," as I see it.
At any rate, she's locked-in for the foreseeable future; this won't matter for another 6 months at least. But that has more to do with long rpgs being her chosen niche than with what's the right move strategically. Kind of a tail wagging the dog scenario, there, which isn't ideal.
Personally I'm down for whatever.
Hopefully this is an acceptable level of speculation. Not to get overly defensive, but I watch a lot of this TV show. I'd have to be totally braindead to have no thoughts about it.
