I'm starting a new project more graphic adventure style and I'm thinking about using Playmaker and Dialogue System to code it. Then I thought about using Dialogue System to display the description of the objects, etc.
Few questions:
1) Is this a smart way of doing it?
2) Is it even possible?
Perhaps that kind of descriptions would be easier to handle by Playmaker? My worry here is having the text coming from different sources (playmaker for descriptions and DS for the conversations), which can make it difficult to manage for translations. Also the handling of the UI, which always scared me.

And one more question: I'm considering whether using different avatars for my characters, with different reactions or just using a single avatar. I have never done this with DS, so I don't know if there is an easy way to change avatars during a conversation. As far as I know, the only way would be creating different "actors" for the same character with the different expressions. Am I right?
Thoughts or suggestions?

Thanks!
