Look, I hate (don't hate) to be That Guy, but if you've never played WEG D6, maybe don't buy this system ahead of people who have and want the 30th anniversary edition. It's unsupported for one, because it's a dead line that they're bringing back one book of in order to basically make $ on nostalgia. Which, as a person in need of parting with $ for nostalgia for my second ever RPG after AD&D, I am ok with.
But there's already strange people who buy WEG books just to look at art, fluff, and stats they cannot possible comprehend because they're not gamers.
Also, quite frankly, the FFG system is just better. It has the advantage of not being d20, and of wanting to be a spiritual successor to D6 WEG. It can learn from WEG's mistakes, in many regards, and there's nothing quite like having to roll 12d6 and tally it up over a few rounds to suck the pace out of combat.
If you're new, FFG RPG.
If you're a crankly old fart, screaming get off my lawn at EU fans who haven't learned the EU is dead, never coming back, and had it coming - this book, except you probably won't play it. You'll just slot it in next to the 18 or so sourcebook you have, and wonder why you bought. Like the consolidated Thrawn Trilogy SB after you already had the HTTH, DFR, and TLC sourcebooks. And so on.
