Related game analogy:

Complete a certain number and types of quests (of varying difficulty) that are from three different worlds: Gene Rale Ducation, Mae Jor, and Requ Irements.  In each world, your character will collect gems which unlocks certain levels--in some cases you need to complete a series of related quests to get to another world. By the end of the game, you will need at least 120 gems before time runs out.  You will also acquire skills necessary to take on the final challenge: Sen Oir Projectus. Lastly, to stay in the game, your game status must be active and maintain a certain average of level difficulty to number of gems or your account is suspended indefinitely.
