Basically, this is the history of Shadowrun.
'Nuff said. I love Shadowrun.
Some language makes it not for the kiddies, but otherwise it's fine.
Oh, and the map is major awesome.
4/5, for not being something I can recommend to the kiddies who are new to Shadowrun.
That said, it has a lot of information you can't find anywhere, not even on Dumpshock's Sixth World Wiki. On one hand, you'll probably not need it, on the other, it's good to know.
