1) Final Fantasy III. Specifically the NES version. It seems a lot of people here played the terrible DS remake and consider "Final Fantasy III" to be one of the worst games in the series because of it, which is a shame since the original is pretty easily my favorite RPG on the NES and rests solidly around the middle of my personal FF rankings.
2) The King of Fighters XI or XIII. The former is just criminally ignored, while some people (*cough*) dismiss the latter because of how awful XII was. Also, the latter is my favorite fighting game of the generation, and the former is my favorite fighting game of all time.
3) Mother. This board generally seems to love Earthbound and Mother 3, so why not? Yeah, there's a bit too much grinding, but that's what frame sk- er, perfectly legal ways of getting through battles faster are for.
