Biomega by Tsutomu Nihei

This is another series by the author of BLAME!
Its seems to be set in the past of that same universe.
Instead of running around in a megastructure this story follows a main character who gets around on a motorcycle.
I think I might actually like this better than BLAME but its not licensed for release in th USA yet.
If you interested in seing it you can find it at OMANGA and Evil Genius
Hopefully it will get licensed soon.
I'd really love to be able to hold physical volumes of this series in my hands.
