To the nitpickers out there I say give it a rest. If the graphics are so important to you, then play only the games whose graphics meets your approval.
I'm not gonna even bother with the rest of your post, but I'm gonna say I know the game is an RPG and I know graphical capabilities has to be limited, but are we really gonna use that as an excuse?
It's like we forgot about that other game which is also completely PACKED with content, that other game that actually has so many enemies on screen at once and yet stays at a constant frame rate, that other game that still managed to look good and highly detailed. (I'm talking about Kid Icarus.) Don't get me started on Dragon Quest 7 or Bravely Default which are also RPGs. They actually look good and are graphical marvels compared to X/Y. This isn't just a difference in art style.
But anyway, that's not what I'm here to argue about. Your quoted sentence, on the other hand, that kind of mentality needs to go. You should NOT tell anyone bothered by this to "take a rest". I'm one of the last people who'd complain about graphics, and I DO plan to buy this game, but am I not allowed to complain about it? Graphics ARE important, regardless of what anyone says, and to me X/Y is exactly why. If the game is ugly, it's ugly, no two ways about it. Now am I not gonna play the game because of it? No. But will I be bothered by it? Yes. And that's why I'm complaining. Gameplay is first but I don't like to play a game that looks like shovelware. I have every rights to criticize.
The graphics have improved drastically since January.
Also, comparing to other 3DS games, this is one of the best looking 3DS games I've seen. I have played a ton of 3DS games, and they sometimes try too hard, and it ends up being less polished. Take Luigi's Mansion, for example. They tried to make things a little too graphically intense, and the frame rate often suffers.
Also, remember that they have to include over 700 3D Pokemon models, each with dozens of different animations / facial expressions, nevermind the trainers and the region.
Did we play the same game? Luigi's Mansion 2 constantly stayed at 30fps (which is acceptable for a slow-paced adventure game) unless you open doors or there are too many ghosts in a big room. X/Y, on the other hand, from what I saw on the videos, struggled to keep at 30fps. Also, Luigi's Mansion 2 was NOT graphically intense at all.
The graphics did not improve that much since January anyway. At least, from what I saw. How is X/Y "polished" anyway?
