The outside of a GM Screen is where pretty pictures and style goes. The inside should be a monument to clinical practicality. We will have to make out own.
I generally don't use screens, but instead, put the charts and tables landscape into a folder. If I can keep my tables down to 2 page sides, I might even buy some cheap file-folders, and paste them onto the insides... more often than not, tho', I wind up with a tables booklet in landscape mode, bound on long edge, in page protectors.
I got one of these.
As do I... two, in fact. It's a pain to load, and I tend to shift game systems twice or thrice a year... and I find, even tho they're landscape, landscape, it's too tall. And my laser printer's toner sticks.
I just made a 3-panel wood L5R 5e screen of 4"x12" (roughly 10x30 cm) 1/8" thick basswood in landscape mode, with tables pasted on.
For me, it's too short. And neither of us even looked at the official one... it's 8x11" portrait.
I'm thinking 3 or 4 panels basswood, with a channel top and bottom added (must borrow someone's shop to do it.... run a rabbet on some 1/4" square stock, glue to top and bottom edges, then glue fabric on the outside, so I can pop in/out cardstock panels as desired... but really, I just wind up putting most screens flat on the table anyway, and my adventure notes in page protectors in one 50¢ 3-prong folder, and system tables in another. Looking at what's available, there are glue-on pockets for 5x8" card in landscape... maybe make a 5-panel screen of those...
I'm getting the Alien screen because I bought the bundle, as I wanted the other goodies. It would be nice if it were useful, too, but my last time actually liking a screen commercially released by the publisher was for FFG Star Wars... but it became obsolete¹ so damned fast, that I'm glad the other materials in the pack were useful...
1: My primary need for a GM screen is weapon and crititcal tables.
