>>42684022pokemon is and has always been a creative collaborative effort with countless steps in the process leading to what we see for any given pokemon design. this process only becomes more complicated as time goes on.
fakemon creators erase all of that and give us step 1s. step 1s from their one track mind.
they also tend to be the same people making the whole game and fakemon is only a bit of what they care about in their project.
plus fakemon designers make pokemon based on their tastes, and no ones tastes is "all pokemon in general"
