The poor difficulty level kind of sucks. I had to purposely hold myself back by not using mega evolutions, turning off the EXP Share, and switching the battling to "Set" mode. The atrocious AI and lack of any sort of challenge in general really didn't help, but it's not going to entirely ruin the game for me. It might sound silly to complain about difficulty with Pokemon, but considering all the new things they have added to the competitive side of the game, you'd think they would do the same with the main game. Just seems like a game a toddler can beat.
The lack of post-game content is somewhat unfortunate. Sure, there's daily things I'm able to do, and there's even the Battle Maison and the Battle Chateau, but it sucks knowing I have nowhere else to go, no secret areas I can discover. It's also shocking how they forgot left out a second round team for the Elite Four, considering they've done this with most of the games. It's not too much of a big deal, but still... It's just pointless to train levels when there is nothing to train for.
Other than this, the game was awesome, and I am glad with some of the changes they have made. It was fun while it lasted, since the experience I've had was one of the best with Pokemon games. Worth the ten month wait? Perhaps, but I had to really take my time to truly digest the game. Guess I'll start breeding Pokemon to train and head off to WiFi battling.
