It brings the number of ships up from like 10 to 131, adds several races and a bunch of variants with different abilities, and increases the difficulty a fair bit while adding a lot of quest chains. Also adds in faction reputation throughout the run so if you just attack everyone it will close off shops etc.

Highly recommend it, like playing an expanded sequel to FTL.
I mean... "expanded sequel to FTL" is all I need to hear
Yeah I was kicking myself on not trying it until a couple months ago and haven't been this hooked on a game for a while.
