This has been floating around a bit on discussion boards. The result of years of research by NeoGAF member Mama Robotnik.
It looks like quite a piece of work they did and brings some understanding as to where Nosgoth came from. Don't be fooled though. Games can get quite far and still be nowhere near playable. A lot of it looks like Shadow of Mordor and it may well be the case that game came out of the experience and work that was put into this one. Sequels are often more polished than their antecedents.
I won't mourn for Dead Sun. It looks fairly typical action fodder and I doubt there's much of a market for more Creedlikes than are already out. Nosgoth, the multiplayer portion that did see the light of day probably took as many man-hours just to see a release. It does bring up the point. How many games out there come so far and never see the light of day? How many developers slave in darkness and fear, wondering if their work will ever feel the Steam on its face? Early access has its charms, not least in knowing that however buggy and unfinished your work was, at least someone played it before a well meaning accountant pulled the plug.
