The campaign also serves as a tutorial (especially the original SupCom one), but on FAF it gets a little buried. On the play screen, there are usually games custom-marked for noobs, but even those are beyond the skills of someone who is just starting and may be offputting.
Also, there is no obvious button on the starting News screen to play a game. Some people might arrive and immediately get lost.
If there is a way to detect when someone opens FAF for the first time, it might be useful to provide some custom links, much more obvious than usual, to a tutorial level or at least a how-to-navigate-FAF video.
