Password system is amazing, love digging out my binder to add my cards in-game. But like most Yu-Gi-Oh games of the era, Eternal Duelist Soul is highly dependent on repetitive duels with the same handful of opponents over and over. If you're just here for the nostalgia and to get some duels in with the older card sets then it's a good candidate, but otherwise you're better off aiming for some duel monster games that are just a little bit more current.
