I don't know. Like on paper the game sounds so much better than all others, but I bought it when it came out(like downloaded it soon as it was on the eshop sorta thing) and it's the only Pokemon game I haven't beaten yet. I just didn't find it super engaging. Something about it just made me put it down and never come back to it.
Maybe I'm just burned out on Pokemon after playing the series for 15 years straight, or maybe it was the game. I probably need to give it another shot one of these days.
I remember not enjoying the trials and finding that while it was nice that we were getting something other than gyms in theory, I liked the idea more than reality -- the trials themselves were pretty boring and felt really bland.
Except for that one with the dancing Hiker. That was the best.
