Tenative completion date?
When its done.
I can not speak for Captain Kwok and I would not presume to.
I feel that it takes time to make a mod of this complexity and the Captain, (Kwok) seems like the kind of person who knows what must be done, and does it. If you look at his models and the work he has done on the mod thus far you gain an appreciation for how much planning he has put into the mod. He is plugging away at it and he has made a considerable advancements in recent weeks.
I am not all that good at AI construction, what I know is from trial and error and examples that other folks have done. Kwok designed the mod, and knows it inside and out, so he is doing all most all of the work on it.
He has nearly finished the Ferengi ship set for the mod, and they look great. He has added new klingon ships, B'rel and K'Vort, and has kept the Star Trek Mod site up to date and looking good. He is plugging away on the data files and AI.
Once all of the little steps and obsticles are out of play, and the peace are in place, then the mod will come together rather rapidly. Until then, it is one step at a time.
