Well this is the GM's Screen Pack.
I own both the pdf version and the physical screen.
I have rated this product at 2 but I would give the physical version another for 3. The screen it's self is well made physcially, heavy duty and good quality and would rate the extra.
Frankly the pdf version is something of a disapointment.
The art on the outside of the GM's screen is cool and all but not much use in a pdf. The Gm's side ... has some of the tables you'll need to run the game but by no means all of them and a bunch more useless art. Oh it's pretty but I want functionalty. I've used this both printed out and the actual physical screen. In both cases I still had to be paging through the rule book to find extra tables. The trickest tables (crit results) are missing whereas how to heal them is. We do get costs for beer and lodging though? Combat in the Witcher is crunchy. I'm happy looking up the price of beer or a room or a hooker for the night but I really could have used the various crit tables right there guys! Frankly if you own the pdf of the main rules it would be better to print out the right tables and use them.
The rules expansion book gives us halflings (booooooo to generic fantasy races) a bunch of npc types (okay I guess) and the new Noble profession (which is pretty good) and some very back of a envelope rules on having a holding of land. The player and gm info is all sort of mashed together and frankly is not all that well edited together.
If I compare this to the only other new GM's screen I've bought lately :- Chaosium's GM's screen pack for Runequest Glorantha. Well it's night and day even at twice the price (for pdf version) it's just so much better. The screen itself has just as much great art but the Gm's side is loaded with really useful information and tables and I didnt have to go looking for extra's more than once in a while. The booklet that comes with it is much larger and has a ton of really well written scenario's and a sandbox setting. Frankly you could get years worth of play out of that thing. And the physical version comparison is even worse as then the price is much closer for two very well made screens. The RQG one is has better info and by being flipped to landscape panels covers a greater estate and just works better, both are of great build quality though, neither is flimsy and feel they's last getting hauled around.
