Well, don’t get your hopes up. Turbine today announced Gaikai, allowing players to trial Lord of the Rings Online and Dungeons and Dragons Online without having to download either game’s client. Playable through your browser, the trial is heavily limited: One hour, due to technical issues that prevent any repeat or extended play at this time.
Currently, the LOTRO trial on Gaikai will allow you to play for up to one full hour. For most players, this will allow you to create your character and complete the starting area for your race. At the end of the trial, you will be logged out from the game and your character and progress will be stored on our servers. You will then be provided with links to download the game client to continue your adventure.
You can find the entire FAQ at the link below, this promotion (for now at least) is only an incentive to give the game a try.
