I heard in a couple places that crescent dyne was about 50-60% finished when it was abandoned is there a place that i can download Crescent Dyne that is like that? instead of just the terrain?

No. Not unless Lethal wants to show you one of its many system maps, which he probably doesn't.

yeah thats what i was talking about, i just want to learn as much as possible about crescent dyne out of curiosity. whenever i see the words crescent dyne I think of how epicly amazing it would be and how mysterious it is that it was just abandoned.

I'm pretty sure it got corrupted or something so he quit working on it.
Though I may be thinking of a different map and person altogether, so maybe you should just disregard my input

It has been corrupted... they searched for a while how to uncorrupt it and then abandoned since the previous save was very far in progress...
I have a version which have some triggers (the leaked version), but nothing very spectacular...
