I remember playing a ton of Shadowrun in my youth, with the very first edition, and I really enjoy the nostalgia trip provided by Shadowrun 2050. It uses the latest version of the Shadorun rules, which is an improvement, although I fondly remember the clunkiness of the original rules... There really should be an addendum allowing characters to die by tripping over their own feet...
The book is logically laid out, with a very good overview of the setting as it was in 2050, and with a very interesting section on the various factions, and why they would use runners, which would be useful even in a more current game.
After that, magick and decking is explained, as it works in that era, with no wireless access.
Finally, there is an overview of the equipment, so that we can all use the guns that we know and love.
The book is well laid out , and very clear, with some very attractive art.
I enjoyed it for its nostalgia value, and I think it would give new players an interesting setting in which to play. A more thorough explanation of how the world and feel of 2050 is different from 2074 would have been a good addition, but other than that, this is an excellent book.
