But its not meant to be fair. I make demos for embedded UI, and really I am the first to get the software. Besides it allowing me to make stuff, the reason I pull down the nightly builds is to try to break it with pushing the limits of the software. I can do this because I know how to use the software back to front.
Thats the same way this is looking. These well known modders have pushed the envelope of modding, most likely using the software in ways it wasnt intended to be used, and bringing up bugs and use cases not seen. If it were given to random people, most likely by terms of statistics, a lot would be just texture rehauls. Bethesda knows this works, its worked forever. What they want though, is for good modders, well known modders, and people who are active at reporting bugs to pull apart their product before it even hits shelves for everyone.
The whole beta thing has changed so much. A lot of people complain they dont get a beta but they dont want it to help out the product, they just want a demo, or it first. The reason for a beta is for bug fixing and stress tests
