This short placeholder review is for the updated version vs. the original version. The layout is better and some rules have been tweaked for what I believe is the better. It is generally easier to find what you are looking for and the contradictions and ambiguities in the old book seem to be mostly ironed out.
The most egregious misstep is the removal of vehicle and voidship rules, especially considering there are still vehicle focused skills and traits (White Scars and Evil Sunz for example).
EDIT: Threatening Tasks also seem to have been removed, but that system wasn't very well designed anyhow. It was basically an overly complicated and cumbersome skill challenge system that can be done much more elegently with a simple skill challenge homebrew.
