How is this asset different from other similar assets?
Pros: Lightweight and Unity-like.
-This asset works directly from the Unity Inspector, without relying on custom editor GUI.
-This reduces considerably the number of scripts, which make it way easier and faster to read, understand and customize the code.
-It takes advantage of Unity GameObjects and ScriptableObjects, so that you can keep using Unity the way it’s supposed to be.
-It’s easier to copy/duplicate dialogues or entire dialogue trees, because they are regular GameObjects in the scene.
-No need to add hundred of scripts to your project just for a dialogue and quests system. Keep it simple!
Cons: If you are looking for a visual asset with GUI nodes, or with a lot of complex features and integrations, there are other alternatives on the store.
