I'm pretty disappointed with how XY seems to have been taken out of the oven before it was finished baking. Some great overhead 3D in some labs and some cool 3rd person 3D in on of the caves, but it's missing from the rest of the overworld and gyms. If they had it sorted for those specific areas, then it shouldn't have been much to push it for the gyms. And how are the badges not in 3D when you receive them? That's just total nonsense. Might as well not show me the badges at all.
I'm pretty apathetic with the new monsters designed for XY, but I've been that way for every gen post-GS. Luckily there is a good mix throughout the game. Could have done without the mega evolutions and some attention put toward bolstering the new line up.
That central hub city is pretty awful. Right up there with the city from BW for terribleness. Would anyone actually be disappointed if they dropped the nonsense design for these hub cities? I was perfectly fine with Goldenrod, Saffron City, etc.
Still having fun with the game. Some phenomenal music at some points. A pretty decent story. Hopefully they manage to tweak the engine before the next release, although its likely t be the hohum Ruby and Sapphire remade.
