Also, am I the only one who refers to Vay as Lunar 1.5 ?
Yes, yes you are.
Mainly because there's such an enormous gap between the quality of the games.
Then again, there's a huge gap between the other Lunar titles and Lunar: Dragon Song as well.
Added in edit: Just to clarify that statement reads back to me like "am I the only one who refers to Cheetahmen II as Super Mario Bros 3.5"
Vay is an unbalanced game with boring characters, a poor story, lousy overall game design, uninspired battles and is as bad as any 16-bit RPG released in the US.
Lunar is basically the exact opposite, a well packaged game with a compelling story (though cliched now, unique for its time), fun battles, fantastic characters, great dungeon and overworld design, great art, and great music.
