I agree roleplay can cover a lot of different things and situation.
My personnal view of roleplay in a world like here, taking in account the constraint and the limit of the game is :
Try to be:
- Reactive to what your partner does in a logic way
Not to be :
- Too much serious
and be :
very tolerant to mistakes that WILL happen, to keep fun and not make roleplay boring or, (worst) "source of stress to do something wrong" which I have leaved myself several times.
I also tend to prefer improvisation than writting in advance a scenario but this is only personnal.
Roleplay can be simple and fun.
