Like Mikey said... anime-based MMOs just can't look as bad ass as realistic. That's why I could never take the Fiesta movie storylines seriously lol.
But I like how anime-based MMO graphics tend to be more vibrant and IMO the costumes can a little more creative. And the fact that its anime-based adds to the imagination.
I'm really picky with realistic. There are some that I like (like Perfect World).
Realistic only if the armour and character's face/body looks good...
A lot of times the scenery/effects etc. look pretty nice (which is a bonus!), but the armour and face is completely screwed over. xD
anime definitely, realistic just eh. Doesn't appeal to me as much in an mmorpg. And like, the scenery is usually all dark and stuff. And in anime it's usually all bright and stuff. And usually in realistic the map is HUGE. Which i do not like at all.
