The problem with Pippa playing boomer shooters is that they require concentration, so I doubt we'd get her usual stream of consciousness insanity if she were trying to avoid getting killed by the 50 enemies on screen. She'd probably do best with horror games or other types that have exploration and otherwise quiet segments.
Regardless, I definitely agree with her about Minecraft. At this point, so long as you don't care about the language or the company, you could probably find a VTuber playing Minecraft every hour of the day, which isn't even getting into the 100s of hours of VODs.
