I beat Legend of Xanadu (the first one) when it came out new, back in the day. All japanese, no strategy guides or walk throughs, or hint of any kind. That's a lil' bit hard core (I had a little translation book where I attempted to translate important text in the game. If was difficult and that last 30+ floor dungeon... ugh). I also beat Emerald Dragon when it was new as well, and that game was a calk walk in comparison.
