Role-playing games often concoct their own rules governing in-text presentation of game terms, and these rules sometimes violate the rules of Standard English. For example, in Dungeons and Dragons, Third Edition, and its kin, initial capitalization is used in the term Hit Dice, periods are omitted from the initialism AC, italics are used for the names of magic items and spells (including spell-like abilities), and so on.
Likewise, sometimes a common term will have a different use such as fortune (not capitalized when used generally for the celestial powers of Rokugan—the setting originally for Legend of the Five Rings role-playing game but included in the 3e product Oriental Adventures—but capitalized when used as a proper noun as in the Seven Fortunes or the Fortune of Storms—as originally used in this question). Also, sometimes a word may be wholly fabricated like nonepic (used in Dungeons and Dragons, Third Edition, and its kin to describe a thing of less than epic stature—as originally used in this answer).
Should an editor make game terms into Standard English for readability or for Standard English correctness?
Note: Although it may seem like I'm picking on Oblivious Sage for daring to edit me or whatever, I'm really not; I appreciate the time taken by anyone to read any of my often loquacious questions and answers and doubly so if they're afterward edited. But I do want them to start out as good questions and answers, and if they're better and more useful in Standard English than in game terms, that's cool, but I'll have to make some mental adjustments.
