Alright, kids, it's time.
As has been pointed out in numerous threads of late, the terminology we use is terminally doomed. They're either poorly-chosen to begin with ("Bangs" don't actually make noise), carry inadvertant connotations ("Simulationism" has nothing to do with The Sims), are perjorative in nature ("Impossible Thing Before Breakfast" discriminates against late-waking Impossible Things), or a deadly cocktail mix of all three. It is perfectly astounding that we have been able to communicate thus far at all. I submit to you that perhaps, just perhaps, we haven't actually been communicating. You never know; there may be some amateur chefs active on these boards thinking that we're talking about cheese souffles and eclairs. I know it took me a long time to realize that wasn't the topic at hand.
In any case, the only reasonable solution is to chuck absolutely everything and rebuild from the ground up. We need to select terms that are clear, carrying no extra connotations, contexts, or relationships. We cannot, absolutely cannot, borrow from other fields like we have been; down this path lies madness and endless metaphorical debates. Any word already in the Engligh language is already burdened with a history of meaning that will only obscure what we're trying to describe. So we must make new words entirely.
I'm going to propose a couple new terms to start off with, and I hope you'll all pitch in, too.
Bargleflap - what goes on in a roleplaying game. Once the dice hit the table, the bargleflap was on!
Zimmy - the people participating in the roleplaying game. The convention was packed with zimmies.
Wangdoodle - any person with greater authority than the other Zimmies. Our gaming group is made of five zimmies, but three of us trade off wangdoodling.
Ansa Dansa Mo Go Fop - the enjoyment, satisfaction, and pleasure that zimmies derive from bargleflap. He's an awesome wangdoodle; he just hosed us down with ansa dansa mo go fop.
Plat - the means by which zimmies acheive ansa dansa mo go fop. We learned some fantastic plat from Primetime Adventures.
Ten-ten tiri - zimmies who prefer ansa dansa mo go fop and plat which emphasize strong wangdoodling influencing the bargleflap. My experience with Dogs bargleflap is relatively ten-ten tiri, but I can understand games where the zimmies plat more than the wangdoodle.
I'm looking forward to seeing your suggestions. The very fate of roleplaying theory may very well rest in our hands.
