Mostly the fact that Yveltal was on the cover. I never use the cover legendaries, but I pick as if I'm going to. Dark/Dragon sounded cooler than Xerneas at the time. (Though now I'm in love with the Fairy type and so I would love to have a Xerneas.)
Agreed. Totally my favorite. I restarted my game a week or so ago (having transferred a ton of my old Pokemon, all holding Mega Stones, to my friend's game) and it's a million times better, for me, the second time. Part of it was that my Chespin had a horrible Attack IV and an Attack-lowering nature (so he was really hard to use), so I picked Chespin again and do not regret it. Playing a second time allowed me plan out my team a little more, and the experience feels more complete this time around. I'm also taking my time with it--I think it's better to do that.
Oh god. I haven't been on the forums since then either. I was so bitter about B2W2 once we found everything out about it that I stopped wanting to come here... and I forgot about all of that speculation up until now! I never did play those games... I assume you didn't either, if you stopped coming here?
Great! I've already beat it once with Froakie and Charizard, so I'm giving Delphox a chance. On my last game, I crushed everything in pretty much 3 days. But now I'm taking it slow, grinding in the Battle Chatue, catching tons of Pokemon, and buying clothes XD.
