In general each player will get a setting primer and a local primer, plus one for their characters race, profession, class, and history. Plus one of "things the player wants to know about". And this works out great for good players that like deep immersion role playing acting out their characters.So, what do you do to present the world to the players? Do you infodump? Do you expect them to research? Do you provide a primer? And how does the players' lack of knowledge interact with the (assumed) knowledge of the PC?
Some players won't read anything and don't care. Until it comes up in the game and suddenly they want their character to be an "expert". These clueless players have much harder time in the game...
In general if your a new player in my game, a clueless player, a player that does not care or other types of such players, I as DM do strongly recommend you play a clueless character. Good players that like deep immersion role playing acting out their characters often do this in my game to get a feel for things.
In general, run things much like a typical TV show....where the players, assuming they are good players that like deep immersion role playing acting out their characters and play attention, will get lots of info dumps and exposition from NPCs and the setting in general.
In general, I will show...often extremely and graphically...local things about the settling and add in plenty of descriptions.
In general, I treat the first little while of the game as sort of an introduction. I take things a bit slow on the setting information side. I don't expect players to know everything. And I won't waste time with "gotthca" stuff the players did not know.
Well...as I'm no Star Wars expert. And have never seen, and never will see the silly cartoon 'clone wars' ever...Let's say that you decide to run Star Wars (Clone Wars era) for a group that has never, ever seen anything star wars. In your one page primer, what key points do you hit?
"It is a time of Galactic Civil War! The Droid Armies of the Separatists against the Clone Armies of the Republic! It's a simple enough War of Succession: the Separatists want to leave the Republic and the Republic will not allow that to happen. Fought on multiple fronts galaxy wide, there is plenty of room for a character to make a name, or some credit coins, for themselves either fighting in the war or doing other things in it's backdrop."
