I had played Stormfall for 3 days so far, about 16 hours total. Game is cool, and you can play without spending any real money if you are patient and you don't mind to do repetitive things. The progression level seems cool too. All about killing a bunch of wild animals, so you can collect items and materials for crafting. It has a nice survival set up, based on a need for food, water, weapons, armor and crafting.
