I've recently bought the third expansion for Faraway.
Rather than extending existing rules (first expansion, "People
From Below") or adding new cards of the standard shapes (second
expansion, "Under Starry Skies"), this one adds a completely new sort
of card, the Spirit.
During the game, two Spirits are face-up, and you can see but not take what's
next on the deck.
Once you have drafted a card (and perhaps played a small Sanctuary
card), if you satisfy the conditions for either of the available
Spirits (central boxed area), you may take it and associate it with
the large card you've just played. At least one of the cards you've
played this round has to contribute to that condition.
Once the Spirit is associated with a large card, it stays with it: its
top tab contributes resources, its bottom tab adds to the score, and
it is flipped whenever the large card is flipped.
I'm looking forward to getting this to the table; alas I like
Faraway more than most of the people I usually play with.
