It feels like the series is two steps away from becoming a singleplayer mmorpg, which I don't hate. Many players however, hate the new 3D artstyle, which is natural as very many 2d games bonked their heads on 2d->3d transitions, most notably a certain blue hedgehog.
Far it be from me to dictate devs how to do their work, but I recently watched a video of Inscryption making-of (A very popular and succesful game despite its genre), and there was a certain fragment there about how the dev made a pipeline with postprocessing effects that turned 3d objects into pixelart at neckbreaking pace.
It feels like something that would really enamour the "in-game" artstyle and feel like afternoon of darkness again, if the devs don't want to go all the way into the DBZ:Fighters anime-like territory (and all the works that it takes) with it.
