YES! The game that saved Squaresoft and brought the Japanese RPG to the US. This game is so much fun and there is no one way to play it. I absolutely loved how you can choose your party; the first time I ever experienced that in a video game! (I played this before Ultima).
I actually still have the cartridge, complete in the box, with the map, booklet, inserts, and everything. This game absolutely must be on GOG and it is one of those games that you just have to play at some point in your life. Just watch out for Warmech!
