this doesn't have to be in the core atow book but I think it should be.
an edit on the char creation rules, and a (few) simplified link notes, where in the examples they make a char both ways.
IE the current char creation is mostly scattered through the char creation chapter.
I would also love a summarized char creation example IE where its all together from beginning to end, and has outtakes (or footnotes) referencing the page that the full information is on.
example start with 4000 xp to make this char, spend basic points 850 * get blah
pick faction /subfaction ** the one chosen provides ...
etc
and then * refer to page x
** refer to pages x -y
another thing I didn't see but would like (altho it may beling in a "gm reference" book or section) is something like the old random encounter tables from 2nd edition basically it was a series of d6 percentile tables that gave broad guidelines for times when the gm wants to just throw something together or when they are stumped for plot hooks
example events are new supplies, new recruits, news of an event, a vip comes to visit, rumors of lost tech cache or similar etc basically a series of do it yourself encounters, events, etc that can be used for a scenario, or a plot hook starting point.
