One star for the excellent craftsmanship. This should prove to be far more durable than my previous GM screens.
One star for the pleasing artwork. It isn't distracting or hard on the eyes.
One star for the neat layout and easy readability.
Minus 1/2 star because the 4th page tables, Experience Point Awards & Treasure Values per Encounter, are not really all that useful in a typical game.
Minus 1/2 star because the table listing actions during combat would have been useful.
Edit: After using this screen for a year-and-a-half, I wanted to add some notes.
I really enjoyed using the Skills section. Some of the skills listed were very useful such as the movement and interaction skills. However, I did notice the lack of appraise, intimidate, sense motive, sleight of hand, & use magic device. While space constraints are understandable, I still wish there were more skills and that the tables had been redesigned with a GM Screen in mind.
The "Common Conditions" section is annoyingly incomplete and redundant in relation to some of the other tables, but including every condition would take too much room. I would suggest using the "Gamemastery Condition Cards," but those too are incomplete and overlap with the GM Screen. Remove "Common Conditions" for the "Actions in Combat" table, but modify the table to consolidate space such as by removing some of the footnoes.
Also, the combat maneuvers chart was useful for some such as bull rush, but useless for grapple. Instead of listing CMB/CMD, have a list of sub-actions for grapple and include feint or put feint in the bluff section.
The attack roll modifiers & armor class modifiers tables should have been adjusted for the screen instead of being copy and pasted from the rulebook. Remove the conditions and list concealment/invisible percentages.
Also, remove the Two-Weapon Fighting Penalties chart. It wasn't that useful since my players and I always prepare TWF before hand and usually don't spontaneously decide to TWF otherwise. However, the Hardness and Hit Point tables have proven incredibly useful!
Finally, this screen has proven to be incredibly durable! Bravo on not only lasting a whole year, but still being in AMAZING condition. However, the artwork got a little old. Having a unique piece to show off would have made this much more interesting.
