Otherland is a great piece of science fiction. It's set mostly in various VR worlds, and one is a Trojan War scenario. The Trojan War, Egyptian mythology, Alice in Wonderland... any world you can think of might show up. I love that series.
Sounds like you're enjoying the anime. Good!
I'm enjoying it, that I am :) I'm about to start the conclusion of the pirate saga. That pirate lady is another multidimensional/sympathetic villain--the writers are really good at coming up with those. BTW did you ever notice how many times Kenshin jumps off a cliff and/or into water either between episdodes or between segments, leaving you wondering what happened to him?--I think the writers must've studied those old cliffhanger movie serials, 'cause they used to do that all the time :)
