lol the people here hating on Abyss while praising Symphonia. Symphonia is a good game, but it's beyond archaic now, and the character interaction is so bland in comparison to the rest of the series that I just skip the skits every time I replay it.
The only thing Symphonia has over Abyss is the dungeons (which were ultimately a chore in the end; Ymir Woods anyone?) and the graphical polish. Abyss' lack of graphical polish is the game's main flaw IMO.
If you can, though, you should play Vesperia. It pretty much improves on everything from the previous games (except for the story, but even so, Vesperia has the best morals within the story), and actually has a likeable child character (unlike Genis and Anise)...
Wind Waker is one of the greatest games ever made. Hoping the HD Remake does it justice.
