Community Admin@ThighWorshiper69 At this point I think it's the 42GB Download and install. It's grown quite a bit as more content has been added, which is likely why there's the "27GB" discrepancy. Unfortunately I don't have any solid info on how compressed the downloaded data is.
And yes, once it passes the mark indicated you can play some of the game content. It's far from the whole game, you'll play as Darth Vader running around a hangar slaughtering rebels forever, but it's something to do while the rest of the content is downloaded.
