The Lord of the Rings Online Developer Diary

Turbine's official The Lord of the Rings Online website has been updated with a new developer diary that covers the mechanics behind a game of "tag" within the festival grounds in northern Bree-land.
Tag a bit too tame for you? Just beyond the Tag ruins, you'll find another set of ruins. Biddy Dogwort can be found to the back side of these, just inside the arch. Speak to her and learn the rules of Freeze Tag. The person who clicks the marker (26.15s, 49.7w) will be It, and everyone inside the ruins is a target. When the It player touches you you'll be frozen in place. Once all players are frozen the game will announce that the It player has won, and rest. But don't despair if It seems to be winning! You can unfreeze a frozen teammate by standing next to them for 3 seconds. Keep a sharp eye out though, as players standing in one place too long risk becoming a target themselves! And unlike normal tag, you can play in three dimensions. Sometimes the battlements are safer than the ground.

As with regular tag, leaving the play zone removes you from the action, though you can still watch!
I think I'll stick with standard questing.
