RPG: Role Playing Game
In Anarchy Online refering to roleplaying your character.
But what does that mean? It's not about equipment, it's not about perks, it's not about being the best, not even about being high level and it's certainly not about cybersex as soo many seem to think of that as the only form of 'roleplaying' their characters. [AFAIK strictly forbidden on all servers]
So again what is it about? It's about living your character. Acting as if you are the person on the screen acting accordingly in any given situation.
I find it is easyer to roleplay if you aren't trying to hard just react as you think you're character should.
As a little help imagine you are a charackter in a movie with no script, the game presents you with a scene but it is entirely up to you how you react to it.
