Lord of the Rings Online (http://lotro.com) is a MMORPG to allow for quests to be undertaken with the role of Man, Hobbit, Elf or Dwarf.

It is designed in the style of World of Warcraft with interactions with Non-Player Characters (NPCs) to guide you through various experiences and quests before undertaking more open-ended challenges in an order you can choose as the role player.
