We’ve released the NS2 "about" page which lists the back-of-the-box features for NS2. Some of it you already know, some of it is new. For those on the NS2 E-Team, these bullet-points are the key concepts we want to get across to people who don’t know about the game.
We can’t say that this feature list won’t change but it should be high-level enough to serve as a guiding light for us through development, just as the original NS1 "about" page did for Natural Selection.
Maybe we should write a story to help visualize the theme and feel as well?
