Lord of the Rings Online - CES 07 Preview @ WarCry

"We can't have the elves or dwarves fighting each other, and you can't play an Orc. The main theme of the entire IP is that you are a good guy battling the forces of evil," said Adam.

Turbine has solved the conundrum by providing what they call "Monster Play" providing a solution which is at once also a unique feature. At level 10, players may choose to play a Monster in a PvP arena. They may perform quests as the Monster by attacking good races - beat up a few hobbits or elves, or fight against other player characters. The "Monster" is not persistent, but the experience gained from the play is applied to their regular character.
