Once I was able to see something it went a little better.

I have managed to add some items, creatures and a trader into the game and have them working now.
I found a video that showed how to create the dialogs for a trader though I would much rather have some documents as I hate watching tutorial videos, they are generally long winded, hard to follow and rarely show what you really want to know. Even worse when the audio is low, speaker has an accent and video is blurry. Much easier to skim over a document and find the content needed.

btw I have no experience with 3d engines but I am a long time coder/developer just never really did anything in this area before. Mostly work on logic and data related code.
