I really don't get the whole "Pokemon Let's Go is the mobile game" thing.
It's Pokemon Yellow from the Gameboy days built in the Sun and Moon engine. The catching part looks like Pokemon Go and some advanced elements like abilities and held items are disabled, but everything else is the same as any other mainline game. Most complaints come from being the Kanto story again, not having areas added for the Fire Red and Leaf Green, not looking like Breath of the Wild, and that it even dares to interact with a cell phone game.
So it’s not like Pokémon Stadium right, you’re saying it’s basically the full “rpg” experience traveling to towns/dungeons, random encounters, catching wild ones, leveling them up, then battling bosses?
