This compilation feels a bit more essential in comparison to the first volume. We get a bit of extra lore (with two possible endings) on a short scenario where you play as Zoe, and a Blackjack minigame where Clancy's life is on the line.
Daughters is definitely worth the trouble here, while 21 feels a bit too random for my personal taste. Still, this just makes me wish Daughters was a part of the original release.
