I think this is a terrible argument because there are such things a technical limitations. If they had made Gen I Pokemon designs too complex, they wouldn't have carried over to Gameboy sprites that well since the sprites were smaller and couldn't handle as many colours. Just look at Molres' RGBY sprites to see what I mean. Moltres isn't what I'd call a "complex" Pokemon, but the sprites still are a horrid representation of it. Just... look at this.
I think Game Freak understood how some of the sprites ended up too, some sprites were completely altered as generations passed. So the Gen I argument on simplicity is invalid because the Pokemon from Gen I have constantly been changing graphical quality. Yes I will admit that if you compare legendaries such as Giratina to earlier Pokemon it will appear that Giratina is "superior" in design, but one has to understand that all Pokemon are all still mostly developed by Game Freak alone each generation. With the increase in Game Freak's graphical designs from Gen to Gen, they were able to make more "advanced" new Pokemon sprites with more increased details than their predecessors.
