"That prize postcard and password...! Did you beat "Legend of Gambla Goemon"!? Those graphics... They express the ambiance of hell so vividly somehow...! And the sound and music really ramps up the suspence and tension when you play it...! It's a milestone in gambling games--a masterpiece! Oh, I have some prizes left from back then, so I can exchange them with that postcard for you!"
