I like the fact that the screen is sturdy and high. The D&D 4E screen was also sturdy, but unfortunately it was too low. I guess some DMs liked that as it allowed them to actually see the players, but I always felt a bit "unprotected" suspecting that the tall player to my left is peeking over the screen. No such problem with the Pathfinder screen!
The art of the screen is also beautiful, although it's nothing new: we've been seeing these iconic characters for several years now.
Now what I don't like about the screen is the choice of some of the tables included. Why do I really need the following two tables during a game session:
Experience Point Awards
Treasure Values per Encounter
These tables are useful before a session, when planning the encounters. I've never in my life used these tables during a game session.
I would rather have more vital tables to the actual gameplay included. I'm missing, for example, the very important table that shows which actions provoke Attack of Opportunity and which do not. Also more conditions could have been included. These were the 2 things that I felt missing after 1 game session with the screen; I'm sure there are more.
As a side note the D&D 4E screen also included the above useless tables. Pathfinder might have taken the idea from there... pity.
