Terminology question for you; what's the difference between calling yourself a DM (Dungeon Master) or a GM (Game Master)? I've seen both terms on this site and I can't figure out if there's an actual difference between them, or it's just a quirk of either time or preference.
To be more specific;
- Is this a rpgSE-specific terminology creation, or do the two terms (Dungeon Master vs Game Master) refer to different things across the entire bredth of rpgs?
- If they are different, how so?
My best guess is Dungeon Master is specific to running a Dungeons and Dragons game, where Game Master is more universal but even there I'm not sure if that's just on this site or everywhere.
