I'm in the middle of writing a novel, so naturally I need to know the topic thoroughly. Since I've pretty much exhausted my bookshelf (and wallet) for other books on the same topic, I thought I'd turn to manga for a different perspective.

If anyone has recommendations for manga (or manhwa/manhua, I'm not picky) where the MC is trapped in a virtual reality game or the main portion of the story (most of the important developments centre around it) takes place in virtual reality, I'd like to hear it. I've already started reading or have finished 1/2 Prince, ID, Yureka and the .hack series but any other feedback would be nice >.<

Thanks!

About books - there's a very interesting series of books by a Russian writer Sergei Lukyanenko, but I don't think it was translated to English So unless you speak Russian or any other language it was translated to, you'll have to wait until it's published in English to read it (some other books by this author are available in English, so it's quite likely). Here's a summary of volume one in English (badly written, unfortunately).

Accel World

One of my favorites
