I would like to mention something as a person who has developed for Game Freak before during the early 3DS era and also another game no one's mentioned in this thread.
Some of the models in Tretta are actually ported from PBR and, get this, Pokedex Pro. Remember that? Anyways, Gardevoir has the same idle animation, as does Charmander in the video on
>>33277557Only a select few models from Gen 6 and 7 are ported over from the games they came from. To clarify, most Pokemon have about 8000 to almost 12000 polygons. For comparison, Lightning from Final Fantasy XIII has over 8000 total polygons, and Alan Wake's character model has over 13000. Some of them are touched up, and yes, they are future proof. That doesn't mean, however, that they can't or wont be scaled up. That also doesn't mean it will happen either.
I'm not leaking anything to you guys so don't ask.
