^Whoops, sorry, I have to reply to this thread for the express purpose of saying that guy had it backwards. If you can play only one, play Secret of Mana -- it's one of the best video games of all time IMHO.
One of the top 100 ever made, probably. But there are too many 'best video games ever' to honestly include it in say....a top 10/20 list, unless you were specifically looking at only one area. --- Waiting for Mirrors Edge 2 and a new 'proper' Shining Force.
I try and avoid comparing games between generations. Zelda II is an awesome game, but how are we supposed to compare it to Twilight Princess without the risk of undercorrecting or overcorrecting for the Wii's advantages over the NES? --- Nagas on a plane! ^_^
