My kids consume roblox and minecraft videos ad infinitum and they are all on Google. I pay for premium to avoid ads so if twitch took this market I would pay twitch.
They also make roblox tiktoks as well but the overall workflow/interface is kind of difficult on the ipad. Really roblox should just make that app for themselves. Build it into the ipad app.
If you run product at either of these companies, implement these things and you'll make a mint.
Also if they could produce tiktok like gaming videos that would probably be popular.
