I had a great PaizoCon last weekend. It felt more relaxed than last year, even though I participated in more panels, because I chose to "run" laid-back games of the revised Pathfinder Adventure Card Game rather than typical RPG sessions. As a big fan of the previous edition of the PACG, and the related modern-day game called Apocrypha, I was eager to give the revised PACG a try. I was a bit worried, because "old" PACG uses a lot of natural language on the cards, but Apocrypha uses so many symbols and keywords that many cards seem utterly incomprehensible to me. The "new" PACG strikes a middle ground, but it's one where keywords feel more like natural language. That makes it much easier to understand and eliminates wordiness. Instead of "Display this card to do XXX," it just says "Display to XXX," for example. "Display" has a specific meaning, but it's precisely as you might expect.

This got me thinking a lot about jargon in RPGs, too. In Pathfinder Second Edition, we're intentionally dialing back a lot of unnecessary wordiness. For example, instead of "the swamp counts as difficult terrain," we say "The swamp is difficult terrain." Things don't need to "count as" something when they actually are that thing. But, like the card game, we have specific words that carry meaning as well, and we try to work them into natural text. You make an Athletics check to Force Open a door, for example, or a Diplomacy check to Gather Information. The capitalization lets you know, "hey, this thing is a keyword," but it also reads like a string of natural English words. 

Consider your use of jargon when you're writing: where can you omit unnecessary words, or work the specific game terminology into natural language? That makes things easier on your reader, and thus smoother at the table.

Another useful trick is this: pretend whatever you're writing is going to be read by someone you know who is smart, but unfamiliar with your specific game (or maybe even gaming in general). For me, that's my brother Robert (whose birthday is, coincidentally, today!). Put yourself in their frame of mind and read through your adventure. If it's still sensible throughout, that's a good sign. Sure, certain parts are going to need a working knowledge of the game system to make sense--stat blocks, usually--but if you're not hiding meaning behind jargon anywhere else, your adventure is going to shine brighter.
