I'm not going to claim is the best Pokemon game, hell, I'm not going to claim is a good game at a lol
But I been playing it for many hours and despise all the obvious problems, I am having a lot of fun with it, and in the end, I think that's the point of a game, for the player to have fun playing it, after all, if it's not fun, why bother?
So while I can understand that a lot of people didn't had fun with the game because of all of the problems, I did had fun.
But on the other hand Gamefreak is never going to fix shit and put more effort into games if they keep selling this much just for being a pokemon game…

Just remember that sales does not equal quality.
