Opt-In PvP MMOs

PvP should be a choice, not an ambush — opt-in PvP MMOs let players decide when combat with other players is even possible, whether through a toggle, a designated PvP zone, or a flagging system that keeps peaceful players safe by default. No random ganks while questing, no getting dragged into a fight you didn't sign up for — the world stays PvE unless you actively choose otherwise. It's the format that lets PvE-focused players and PvP enthusiasts share the same game without stepping on each other. This tag covers MMOs with opt-in PvP, from flag-based systems to dedicated PvP servers and zones layered on top of a PvE-safe world.
