Steam now offers Castaway Paradise Complete Edition for Windows and OS X, a life simulator in the vein of games like Animal Crossing and Harvest Moon. Here's a launch trailer, and here's a bit on the game:

Castaway Paradise is a life simulator similar to games like Animal Crossing and Harvest Moon. This makes Castaway Paradise the first and only game of its kind to be released onto Steam. You get to enjoy life on your very own tropical island. You can customise with thousands of items, catch bugs, seashells and fish, talk to the other villagers, grow trees and flowers, and much more. It’s the ultimate sandbox sim.

After three years of hard work, Castaway Paradise launched on Steam with a 10% discount. During the launch month players will get exclusive DLC packs completely free of charge. Throughout the year Castaway Paradise will give players hundreds of items without any additional payments. Castaway Paradise is a premium game, there are no micro-transactions.
