Huzzah the wait is over!
It was great to get this into my hands. It's been more than 6 years since I started warning my FLGS; "Hey...Just so you know...Interstellar Operations is supposed to be coming out someday. Make sure and order me a copy, okay?"
I had the beta and I didn't realize this; but I was entitled to the finished PDF as well, but I have a much easier time with dead tree books than digital. I found a few small typos and printing errors on my brief perusal, but just to have pretty much all of the construction rules(anything left out?) in finalized form is thrilling.
Now, if only we had some software to bring this stuff to life in less than an afternoon! HINT-HINT!
As usual; the fiction itself is a draw as well!
