I used to love writing about new Humble Mobile Bundles, the Android equivalent of HB's excellent pay-what-you-want software packages that benefit charities, and great indie developers. Sadly, those days don't come as often anymore, but this latest one — board game-themed — is worth mentioning.
Carcassonne: fine. Scotland Yard: meh. Great games, I'm sure — but you're really here for Catan, one of the greatest trading strategy board games ever conceived.
Catan, along with Splendor and THE aMAZEing Labyrinth, are unlocked when you spend more than $3 on the bundle (remember, it's pay-what-you-want); Ticket to Ride, San Juan, and Galaxy Trucker are also part of the deal.
