Mob

Short for "Mobile Object", this is a term from all the way back in the days of MUDs, or Multi-User Dungeons. These were text-based games played on Bulletin Board Systems (BBSs), and pre-date the Internet.

Refers to anything in the game that is capable of movement, although movement capability is not universal (see Mobject).

Technically this also includes NPCs, or Non-Player Characters.

Today, most players mean a Monster when they say Mob.

Examples

 * "These mobs are too hard for me"
 * "The mobs on this map all look very cool."
