With so much content available from D&D there's a seemingly endless list of possible additions available to the game such as new quests, races, classes, feats, prestige classes, spells, and custom esthetics such as armor. Obiviously there is no lack of material for the game to expand upon. What then is the best way to determine what content gets added soon and what gets added much later?
Why not allow the player base to vote for the game's upcoming content releases with Turbine Points? Turbine sells the points and the players vote for what they want by pre-ordering the content under consideration for development. Turbine collects the finances up front for each specific project, reducing their risk and by judging sales when to release it. Players know from their purchases they are actively opening the valve for more specific content.
Here's an example of how to use the pre-order system with the highly desired druid class. Perhaps the class will go for 1000 TP when it goes live. Turbine could create a pre-order druid package for 200 TP which includes a 20% off druid class discount or an account bound "pre-order only" class unique item such as a hide armor for the VIP players since the druid class would be free for them otherwise on release. Turbine determines that after 4000 packages are sold that there is enough interest to make the project financially sound with already $8000 earned and another $32,000 in likely future sales. They move druids up the development time table and hire another programmer to help speed up the total project time. Turbine then announces that druid pre-orders have "sold out" and players happily know that the next awesome thing is on its way.
Turbine was the first major player in the micro transaction funded MMO. Pre-orders would make it a first in the player content determined MMO. Players want the power to determine the future of their game, developers want the capital up front. Using the pre-order is a win win for everyone.
