It is not often that I will come out and endorse a project pre-release. That is something I will generally reserve solely for CD Projekt, but I'm willing to put money on this turning out well. If you guys want to help out you can always download the masterfile, install it and give feedback.
If you don't want to go through a buggy project to help out you could always just download Morroblivion to get a sample of a slightly older version of their work.
All in all, there is not much bad to say here. You want something done right? Do it yourself. Want something done right with technology? Take it apart and see what you can rebuild with the rubble.
These guys get it.
