Albion Online for iphone from Sandbox Interactive GmbH

Albion Online is a cross-platform, sandbox MMO where you can explore a vast open world. It’s a player-driven economy where you craft the items you use. You are free to do as you wish. Explore the world, meet other players, fight, or go hunting with them. The game is entirely optional, and you are free to play or not.

There are no quests, no NPCs to speak of, and no pressure to complete tasks. If you want to gather a certain type of item or do a certain quest, you can do it without restriction. At any point, you can go back to where you started. You can explore the world, craft, and gather as you see fit.
