The word «security» comes up multiple times because
traditional offline play and modding outside a rather difficult to setup

traditional MMORPGs — they're MOBAs, online dungeon crawlers, ARPGs, online shooters, survival
sandboxes, and other
games that tread into MMO territory but aren't full MMORPGs.
