Give the opening an immediate purpose
Start by deciding what your character wants right now. Add where the encounter takes place and why you are there. Those details are enough to begin; the history of the whole world can wait until it matters to the conversation.
For instance, you could be a new technician asking an observatory's director why the telescope has stopped following its schedule. Describe what you noticed and ask for help investigating it. Both participants then have something to do, with the explanation still open.
Make speakers, actions and preferences clear
Keep spoken dialogue distinct from descriptions of what you do, using a consistent format. Stay with a recognizable point of view so the character can tell whose actions you are describing. Frequent, unexplained switches between first and third person can obscure that distinction.
We encourage you to state boundaries and writing preferences plainly. You can request brief dialogue, a slower scene or fewer descriptive passages. If a response misses the mark, describe the change you want to see rather than leaving the character to guess from a general complaint.
Carry the right details into the next scene
At a change of location or time, a brief recap can reconnect the story to its unfinished goal. Put lasting background information in a Lorebook. Details that change as the plot unfolds should not all become permanent traits in the character's personality.
For consequences such as changing resources or story state, a Rulebook can add tracking. A simple conversation may not need it at all. Use those tools when they serve the story you are telling, without adding a system of meters to every exchange.
Questions
Can a roleplay include an AI girlfriend or boyfriend?
Yes. Choose or create an adult fictional character and make the relationship part of the premise. The interaction remains fiction; it does not establish a real person's identity, consent or commitment.
Am I limited to the story in the greeting?
No. The greeting opens a situation rather than fixing every outcome. Your messages can add events and decisions, while a clear character definition helps those developments fit the character.
