I loved the Disney Afternoon Collection. So glad Capcom put that out. Whilie many people have fond memories playing Mario and such on the NES, a lot of my nostalgia comes from the Disney Afternoon games. DuckTales in particular is pretty amazing. I would say you should try Chip N Dale Rescue Rangers, but technically that came out in 1990.

If it weren't for Animal Crossing: New Leaf, DuckTales remastered would've been my GOTY for 2013.

I'd say stick with the pixel remaster for Final Fantasy. The original NES game had too many things I find annoying. For instance, if two characters are chosen to attack the same enemy, and the first guy defeats it, the second guy won't auto target another enemy. He'll just swing his weapon and miss.
