It's hard to judge based off of just one manga one a couple of episodes each, but i still think i like Ceres better.
I don't know if it's just cause Akiko put it into my mind, but Fushigi Yugi does seem a little, um, um, damn it, i know what that word is. Wish fullfilment i guess. Normal girl gets transported to a strange land where there are lots of cute guys who like her and she gets to be an important and famous person and all that stuff. It's not too bad, but i was kind of picking up on it.
Ceres seems much more real and there's more conflict. Oh, and it also has a really cool ending and ending theme =)
Now i've got to decide if i'm going to buy Ceres one DVD at a time, or wait for the boxed set to come out.
