I’ve noticed that different games like to use different names for the same (or similar concepts). Guilds for example are known in Everquest 1/2 and WoW as guilds, Lord of the Rings Online calls them kinships, and Warhammer calls them Regiments (or sometimes guilds as in Living Guilds, they’re a bit inconsistent). Warhammer also gets confusing because they sometimes refer to their different races (such as dwarves, high elves, etc.) as Armies and sometimes as races. Classes are sometimes known as professions. Talent trees are known as specialisations.
Sometimes these different names stick with players, and sometimes we revert to common nomenclature. I think races will always be known as races rather than armies. Although I really like the idea of guilds being known as Regiments, I suspect it’s mostly the RPers who will go with that and everyone else will call them guilds.
Back when WoW was in beta, the old warcraft players referred to mobs as creeps, because that’s how they were known in Warcraft III. That didn’t really gel with the player base, who like their mobs to be known as mobs (it’s an old MUD term). They also like their mezzes to be mezzes (mesmerise, a form of crowd control spell from Everquest), their procs to be procs (this is more complicated and refers to a type of magical weapon which occasionally produces some special effect like a lightning bolt or debuff when you hit something with it, again this is an old MUD term), and their NPCs to be NPCs (another old term from Dungeons and Dragons).
Do you like the Warhammer specific terms?
