How the player chooses to proceed through the missions, though, is completely up to them. If a particular quest is too tough at the moment, the game offers an unlimited number of random quests to build up your character -- or you can just explore to your heart's content. Better still, when you've explored the whole world, you can restart the game again. All your character's experience and equipment will be intact, and the difficulty of the game will be raised to become appropriate to your new level.​
