Tool for developing branching dialogue. It’s designed for both video games and training. There are more features here than what I would need for most scenario-based training I develop, but for something complex this would be a great way to create and test a conversation. It also exports to a very clean screenplay for actors. The free version is only for personal use, but the Indie license is only $60 and would be worth it for a complex enough project. I can usually keep it all straight in my own head in Word, but I’ve had problems getting actors and developers to understand how the pieces fit together. The simulated dialog might be enough to help others see the flow.
