You really shouldn't. The game is boring with basically no plotline whatsoever coupled with a pathetic "rival" and insanely linear progression. There's no freedom until you've beaten the game and everything you want is after you've beaten the game.
Most of the game I hardly gave any fucks about and all I did was wondertrade or breed. The only time I actually had any type of challenge was the wishiwashi totem where it kept one shotting most of my team with water gun. Even if it wasn't effective.
This game likes to add artificial difficulty to try to make you think there is challenge when in reality, there isn't.
I hate fairy types to no fucking end but I honestly find X and Y to be a better game. The only thing I truely liked about this gen was Team Skull and all of Team Skulls music themes.
