So it's not the first time that Pokémon sprites from other games have been recycled for use in new ones (like DP 3rd Gen. sprites being used in HGSS) and such, but I can't help but feel that they made some odd choices over which to use for all Pokémon from 001 to 493 in the dex, non-Unova Pokémon sprites. I'm not complaining, don't get me wrong, but I'm curious as to why they used some of the sprites they did when there were certainly better to choose from. From what I've seen they mostly stuck with DP sprites and Platinum sprites occasionally, while HGSS sprites which I feel were vastly superior. I mean, weren't some DP sprites notable for being lackluster? While Platinum had to fix a lot of them? HGSS used Platinum sprites over DP ones. I mean, I haven't looked at all the Pokémon sprites, but this is just the general impression.
HGSS sprites were so awesome and natural, but a lot of them didn't get carried over. Gyarados, Mewtwo, Moltres sprites are just so much better than their DP sprites pose-wise and proportionally speaking.
I don't know, how do you guys feel and why do you think they opted out of HGSS sprites? Was it because DP and Platinum sprites were easier to fully animate?
