MCV has word on the results of Turbine's decision to drop subscription fees for The Lord of the Rings Online, saying the move has doubled the game's revenue. Word: "In addition, a million new accounts have been created and 20 per cent of the game’s former players have returned. Peak concurrency has jumped by 300 per cent and the total active players count has increased four-fold."
How do you get more revenue when the game is free?
Only the absolute minimum of the game is free. Many of the areas/quests in the game require "points" to play. While you can get points from playing, it's faster to purchase the points.
