A boxed copy of any NES game is always a cool find these days... Maybe not a worth-its-weight-in-gold one, but cool none the less. As for the game, I've heard the name before but I've never seen it played. Most NES games in the RPG genre are fun though. Even if only for the, "lol look how bad this is," effect.
Also, I had no idea you still were on the forums, banditpaw... I saw your name on the front page and was like, "Oh Heck yeah, I'm posting today." Feels like middle school again.
