Hello! I doubt the people are dead, but the project surely is. I know that at least one of the people were picked up by the ghosts of the precursors project. I wouldn't even know how to dig up the old code, assets and other resources. There was a story structure all mapped out, at a high level, but I doubt it is still in existence - in the cloud or elsewhere.
In terms of actual fleshed out dialogue, what you see in the demo is what there is. (unless other writers know different!)
It would have been great to finish p6014, but in the end it was too resource intensive for the volunteers, and especially me as project lead. I am glad that some people got some joy out of the small bit we did finish.
And it did lead to Damon's HD version, which is excellent.
Ghosts of the precursors is due out this year, so that is the thing people should get excited about :)
