Sorry if I necro'd this thread, but I feel that those two words can be quite ambiguous. Fans of this saga (and other works of fiction) tend to have their own personal set of standards rather than a unified "official" set of rules and standards of what constitutes as "lore". Of course, it's a complete violation of "lore" if anachronisms are introduced such as electronics or assault rifles, unless it's for comedic effect or for unusual screenshots. But what about characters, especially followers? Or houses? I find it rather frustrating to try classifying my mods through those "rules", it's becoming frustrating no matter how much I try to put backstory and explanation behind those mods, that I don't bother using the "lore-friendly" tag because end-users, just as I said earlier, have their own stronger definition of "lore" because of mods and more than what Beth defines as "holy writ": their "lore" can be a dark, bloody, cold, and dirty Skyrim. Or a Skyrim with vivid colors, clear skies, and characters in the pink of health.
