But I do not need the manufactured screen for that, do I?
Nope. I'm perfectly happy with homemade screens. Or sometimes no actual screen, but using other techniques to achieve the same effects.
Really, what are the tables good for? I never get this idea? The important numbers I know by heart, the unimportant I make up if needed. Which tables do you check on the screen actually?
I don't have the best memory. I don't always improvise numbers well. I have to remember & improvise enough. When I can have a quick reference to rely on, I like to. e.g. In the current campaign I keep forgetting the modifiers to the party's movement rate for each terrain type. So, when they move from one terrain to another, I check the table.
But the quick reference isn't the purpose of the screen for me. It's handy to put them on the screen if the screen is there, but I can just use paper on the table for them as well.
Oh and one more... what is the whole thing about covering the rolls. I knew, I did it myself, but is it because of the surprise or so that you can forge the rolls or not reveal the monster stats or why? Is it because you want to save the players in case you roll to good, or rather make them hard time even if you roll bad. Or is it because you want to make the encounter really cool whatever you roll (and then why to even bother with rolling dice?)
Yeah, I tend to roll in the open these days. So, my screen isn't for hiding rolls.
(Actually, I do still make a lot of the "roll just to make the players nervous" rolls behind the screen. But that's really just a gag at this point. I obviously don't even look at the dice half the time I do that.)
When I'm a player, however, I don't mind the DM fudging rolls in my favor, but I don't want to know when he does it. So, if he's going to fudge a few rolls, I prefer him to roll behind the screen.
So what is left? Maps probably. What would happen if players woud by accident see the game structure (be it dungeon of set of mystery clues - both could be made in form of map?)
That's what I use a screen for. In my experience screens don't prevent the accidental glimpse. Screens prevent the consistent glimpses or plain views.
