you dont need root for these things. just download the fdroid apk from its website, open the apk (you probably need to allow installing third party apps in the settings, which come disabled by default these days), then search for libretube or newpipe inside fdroid after letting it download its app catalogue (it may seem confusing that fdroid seems empty at first, but you may just need to slide down to update and wait a second for it to download the catalogue).
seems to me like AAA games always were about demonstrating new game technologies, showcasing a new graphics engine or something, not about entertaining/fun games. Like that Crysis franchise from around 2010, everyone wanted to have a pc that could play crysis, but nobody actually wanted to play that game.
