Appearances in anime are usually more symbolic or portaining to the artstyle. they have nothing to do with realism o_o

If you want a realistic artstyle, watch Miyazaki's (i think that was the director) films. I.e. Castle in the Sky, Spirited Away, etc. However, the stories in those are wildly fantastical... so i guess you cant get the best of both worlds.

oh, i dont really care if they are real or not
just pointing that pretty much every mmo, video game, tv show, and anime is not realistic

Pwned. Small eyes rule...
