I don't have a clear favorite part in FF6. I love this game so much. There are quite a few: Cyan going solo against the Empire for poisoning Doma (I like that amounts of rage, especially when the beloved is at the brink of dying...that kind of rage provoked by such action is inspiring), the entire scene in Vector (that darned mission was way cool. Few people introduce to a country and wreak havoc with so much ease), awakening the Espers (nonsense destruction is always a plus

) , etc.
Oh wait...I know now what's the absolute best part about FF6 (I can't believe myself...)
Its Terra. Yes, its a character the part of FF6 I love the most. Like everything about her, except Edgar flirting and all that with Leo.
