What do people think of Sun/Moon?
I last played G/S/C on the GBC and quite enjoyed it, and before that, B/R/Y on the original GB. I caught all 150 Pokémon on Blue (yay for the Cinnabar Island coast!) and got Mew through an event. I later got Celebi in an event for Crystal and with trading from Blue, got to around 200/251 Pokémon caught in the Pokedex.
I kind of gave up on the series after that because it started to get a bit too repetitive for gameplay and the Pokémon available just kept increasing with it not being possible to catch them all on that generation. To the best of my knowledge, there are ~720 Pokémon in X and Y but you only get about 300 of them without earlier games. (Correct me if I'm wrong. Also something about the 'game' Pokedex being limited to in-game Pokémon and the National Pokedex containing the full list of entries?)
Sun and Moon seems to deviate from some norms (e.g. 8 gyms). It also goes back to having a single Pokedex that only lists Pokémon available in those games? For some reason, it's really piqued my interest. Is it good for someone who has been away from the series for a while? Should I get it?
