Aside from PLA, Pokémon games work better with routes. Ask me to remember a route and I'm sure I can because the music and look usually have their personality. Ask me to remember random copy/paste area in Paldea other than the bamboo forest and snowy mountain and I can't do it, despite playing Violet for as long as any other game.
No, it’s super difficult. Just like it is for any streamer or youtuber. You have to just get really lucky with the algorithm. You still have to make quality videos, have a good editor, be entertaining etc. I personally could also never kiss the pokemon company’s ass for a couple of freebies.
You don't really have to be entertaining to be a Poketuber but other than that yeah it's definitely a lot of work If you wanna make videos go for it though
Sleep is much easier to open up and play for only 5 minutes at a time. Much more laid back than Go due to a simple concept.
