This category is for players who consider themselves casual roleplayers. That is to say, they enjoy acting "in-character" and might play out a story, but they don't wish to embrace hard-and-fast rules about continuity or play style. For example, a "serious" roleplayer might have rules about how to treat in-game functions (the chat window is a radio/comms system, the in-game email is a message server, security level or PVP match dictates who can beat whom in combat), but a casual roleplayer is more likely to leave these things undefined, or go with whatever suits the story at the time.
This tag does not preclude mature/silly/dark/adult roleplay. It indicates the attitude of the player, not the nature of the content.
