I think updated graphics are fine. For instance, the GBA remake of final fantasy 1. I never would have played it on the NES, it was too hollow. Solid black backgrounds, every battle, yay boring. The 8-bit graphics were cute, but to be honest a little hard on my eyes. having everything updated with shading and backgrounds helped a lot. Additionally, the music was way better.
Also additionally, I liked the added content. Know what's way better than grinding the same monsters on the same patch of field for hours? Fighting ALL OF THE BOSSES from ALL OF THE GAMES up until six. That shit was so cool.
