For the games I've played, of course. And then there are games I've heard that are amazing, such as Suikoden II, Xenogears, Legend of Dragoon, Vagrant Story, Parasite Eve, Persona 2, Breath of Fire III, IV and V, Saga Frontier I & II, Wild Arms 2, Legend of Mana, Vandal Hearts, uh... probably others. You guys might be able to correct me if I got any of these wrong. Not bothering with whether or not they are ports... just going for pure "how many good games during a single console generation".
