They hadn’t announced this, but… I bought Wing 2 with gold last week. Today, I checked the “Get the Full Adventure” button (out of idle curiosity), and the price to unlock the full adventure was only $14.99, not $19.99.
So it looks like the price to unlock the full adventure–at least for the time being–is ~ “$5 per wing you haven’t already unlocked”.
(I expect that to change at the end–if you’ve bought wings 1-4, I’m willing to bet the price for wing 5 will be "$6.99, take it or leave it.)
My point was, the announcement was just: “$6.99/700G per wing, or $19.99 for the whole package”.
So I assumed that the whole-package deal would be bad for me if I’d already paid gold for a wing, since I’d be paying dollars for the wing I’d already unlocked. But it looks like they’re lowering the “rest-of-the-adventure” price for people who’ve already unlocked part of it.
Yea, no. I can see the amount of effort in a lot of small corner case interactions (e.g. 5 Millhouses making Millificent concede) and I think the price is fair.
