Role-playing vs. multiple identities.
Talking with Rick about masks, roles and theater and reading Torill's dissertation (Pleasures of the Player: Flow and Control in Online Games, 1,6MB pdf) connected when I realised that I do not really enjoy role playing while I like playing with my multiple identities.
Drawing the line between these two is not easy, but so far I think about multiple identities as different sides of myself and about role-playing as taking a role of someone who is not me (elf assassin for example :). Need to dig into theory to get it clear...
