Umm... 'Kay... Well, from your list, I have watched FMA (but never chronologically... I want to get the episodes, so I can... And I want to get Brotherhood!), the Melancholy of Haruhi Suzumiya, Digimon, Pockemon (yeah, I like spelling it like that now), Sailor Moon, Yuugi Ou, Yuu Yuu Hakusho and Wolf's Rain.
I've seen Naruto, but don't really like it. And I've only watched the first 13 episodes of Soul Eater and not read the manga. So I want to at least see the end of the series first. Without spoilers no less.
So... That's difficult a choice to make. I don't really feel like Fullmetal Alchemist, so that can go off. I'm not quite into Wolf's Rain at the moment, I don't think.
