Have played a couple of games, using the first adventure of the plot point setting. I had to go to the web site for some errata, and found it easily. A very interesting setting that isn't quite steampunk, fantasy or standard SF, but an interesting amalgam of all three. The art work in the main books is ok, and does illustrate ideas very well.
If you are looking for a fun Steampunk variant, this is probably it. The players guide is the first section of the overall rule book and could be printed separately from it, so nor real added value there, except you can share the file with your players without worry that they might "accidentally" slip into the GM section. The printer friendly versions are nice to have. The paper figure are nice tri-folds and have quite a variety, and plenty of copies of things that might be encountered in mass.
I have not dug into the Odd jobs or Darksummer nights, but on casual perusal, they seem to be more of the same.
Overall, a nice purchase, and if you are looking for a quite different setting, this might just be it!
