Starting this fall Turbine's Lord of the Rings Online will be free to play. The game will make its money by selling thousands of "convenience" items as well as expansion packs, premium content, additional character slots, potions and character customization. Beta kicks off on June 16.
This might make me play again. The starting areas were great in giving you plenty to do but not making you feel overwhelmed. However after that 2nd town or so the world just opens up too much, too quickly and I felt like I had way too much to do. Being free might make me feel a little better about being bogged down.
