Before the release of the game, I was contemplating on removing my pre-order but after a couple of weeks playing, I am lucky I did not.
The game is not perfect but nor it is the "worse" game as negative reviewers say. I don't want to list much as to avoid spoilers but what I can say is that new players will really enjoy it and maybe even some long time fans of the game will like it.
Highlight of the game personally is the wild area where you can catch all the wandering Pokemon in the nice scenery. The only major negative thing I can think of is that it can be very "hand-holdy" in the first 30 mins of the game.
