You hear a lot about role play on SecondLife. There are two kinds of role play:
Immersion role play is done for the benefit and entertainment of the role player themselves. Often their role play character is an aggrandized version of themselves, either as they are or as they would like to be.
Immersion role play is usually done is secluded areas where they don't have to worry so much about people not involved in the role play spoiling the fantasy.
Performance role play is done for the benefit and entertainment of the people watching the role player. It's similar to improvisational acting. Often the role players play characters very different from themselves or anything they would like to be.
Performance role play is usually done in public areas and often in areas where you wouldn't expect to find such a thing, like welcome areas.
Of the two, immersion role play is far more common in SecondLife. There are whole sims dedicated to different versions of immersion role play, like vampires, goth, furry, western, etc.
It's possible to find performance role players within the immersion role play communities, made to entertain the other members of the community and fill out roles in their narrative that nobody wants to take as their main character.
