If you find the updates are getting hard to manage and you're not enjoying the game, you might want to take a break until the rulebook ships. I imagine there are more updates coming, so it's not going to get any easier for you.
I imagine we're only going to get a couple more updates, given the cut-off date for providing direct feedback to FFG is December 1st.
Probably an update either tomorrow or a week from tomorrow, possibly one just before Thanksgiving, and then likely a final update roughly a week after the December 1st cut-off date.
I will agree with daddystabz that some of the updates are bit tricker to keep track off without drastically marking up one's copy of the book, such as the recent talent tree updates, the near-total revamp of Force power upgrades, to say nothing of the changes to some career skill lists due to the removal of Surveillance as well as the alterations to several talents.
