Start with a situation that gives each character a reason to respond. Then decide what they want, what they do not know, and what could make the situation harder.

For more character-focused scene starters, see 265 Best OC Writing Prompts.

How can roleplay partners share control of the story?

Agree on which characters each person controls, what kinds of conflicts are welcome, and when a major change needs discussion.

What makes a plot work for long-term roleplay?

Give the characters goals that can change, relationships that can develop, and conflicts that produce new choices rather than repeating the same problem.
