In EQ 2 they start you on an island and give you quests that get you started with your character. You can choose to leave the island immediately by boat. But if you're new to the game it is always nice to go through all the quests and get a feel for the game. I think this is what they offer as a free trial as well. Once you leave the island you can't go back.
And I think that is what happened to me in LOTRO. After spending time in Archet (the man/hobbit starting area) I was given a quest that told me to "make sure you finished all your quests because once you do this one you can't finish them". I wasn't entirely sure what that meant, but I took the time to run around and do a few more quests that I had. In an instant text quest world, some players may miss this.
I won't spoil the quest, but I think it was a very nice touch before pushing me out of newbie town into the unknown that awaits me. I'll just say this, I enjoy having some impact on the world.
