Just something I wondered, there have been so many differend artstyles over the course of this franchise, so what are everyone's personal preferences here?
I for myself do enjoy the artstyle introduced in 20th Anniversary the best, since it is essentially a refined version of the Fever 2- PP7, with added shading colors that pop even more and a more three dimensional feel.
Outside of that I also like ~n's artstyle, it's very unusual for the series, but I find it refreshing, both with ingame visuals:
and official art, as well as character design (you won't ever convince me this is isn't the greatest kid Lagnus design!) :
If we take Madou into account as well then I'd certainly count ARS as well:
especially with the sprite art:
(Seriously the detail in his mugshot here is friggin' lovely)
PC98 Madou 1-3 are also neat for being a very different:
But yeah, those are the ones I like the most, but they are far from the only ones, honorable mentions go to Sun Fever 2/15th Anniversary and Waku Waku Puyo Dungeon.
