I haven't been an early adopter of the previous LCGs so I'm curious how long it took for those FAQs to come out... days, weeks, months?

Difficult to guess and to remember...Other LCG were bit different, cause we already had some FAQs, even if LCG faq is independent from the others.

Anyway, in CoC we got a couple of FAQ in a year. In GOT we saw 2 LCG FAQs since the Core Set was out.

But I guess we'll get it soon. Now lots of players got the Core Set everywhere around the world.

I try my guess: couple of weeks. ;-)
