Here's the neat dialogue editor I made for Lunchtime RPG. The dialogues are stored in Scriptable Objects, and I made this awesome Graph View for displaying and editing the dialogues. This was a bit of a big project, but I learned a lot about editor programming in Unity while doing it.

And here's a video of the above dialogue taking place in-game. The bird needs a worm as payment for its shuttle services, and the dialogue will go down one of two branches depending on whether or not the player has a worm in their inventory. If the player chooses to pay up, then the worm is removed from their inventory, and the bird walks over to the edge of the nest to prepare for departure. All of this is easily configured thanks to the dialogue editor and Unity Events.
