Not that other games are in particular need, paper mario is particularly not in need, due to its art style, theyve aged amazingly. Heck even in this trailer a lot of the environment has distinct polygon edges, because it was always intentional, its folded paper.
I guess sort of like the original Toy Story shouldnt ever need a remake because the plasticy old 3D look was intentional for a movie about toys.
I think first NES Kirby was the easiest NES game for me.
