I'm torn right now! This is the first Pokemon game since RB that I've gone into blind (well, the anime in syndication kind of ruined RB for me, so technically...my first?, and I'm absolutely loving exploring everything in-game and taking my time and experimenting with new Pokemon without using guides/Smogon.
On the other hand, I WANT TO MAKE MY COMPETITIVE TEAM SO BADLY! I've already soft-reset countless times for good natured Tirtouga, Zorua, and Victini and I'm already making up my mind on what I want to EV train first.
In other news, I used the GTS a lot in DPPt, but damn, nothing feels better than breeding some Tepig, throwing them up on the GTS and receiving everything you could possibly want in mere seconds.
