Free players have access to the entire game, but can craft only eight hours a day, and craft, harvest, and gain XP at a slower rate. There are various subscription tiers beyond that, and there are also items that can be purchased, including cosmetic clothing and boosts to XP gain. The $10-per-month Survivalist subscription gives you more crafting slots and speeds up times of actions (like harvesting or crafting) relative to free playing. The Wastelander tier ($15.00 perm onth) gives you everything Survivalist does, plus much faster crafting and XP gain, and a 15% discount at the cash store. The Commander tier ($30 per month) gives you an "aura" that enhances the action speed of allies near you and a 20% discount at the cash store, plus the benefits of prior tiers.

If a post-apocalyptic sandbox game with an FPS combat interface and deep crafting appeals to you, Fallen Earth is worth giving a shot.
