There is a Lord of the Rings MMO (like World of Warcraft) and a guy made a video recording a walk from the Shire to Mordor. Like you can just walk from the Shire to Mordor in the game. And it's almost 10 hours long in real world time to do that! But on top of that the whole journey is narrated by the Lord of the Rings audio book, with the relevant parts of the journey.
Incredibly relaxing
I don't have experience with the LotR Online outside of small clips here and there, but for the past 5 years or so I have been enjoying a bit more retro LotR "mmorpg", a free-to-play MUD that has been in development since 1991 or something: https://mume.org/
In MUME (Multi-Users in Middle Earth) getting from Bree to Mordor by walking won't take you 10 hours, but maybe 10 minutes at most. However, the trip and the destination will be full of dangers, whether it's from pve or pvp side of things.
As a side note, MUME is being developed by volunteers, and I believe the game itself is still ran on some Swiss University servers, where it all began, heh.
It was simply magical and I have many good memories venturing through middle-earth and meeting fellow chars.
I literally guffawed and thought, "Well, that's one good way of avoiding the dark riders." Makes that dramatic jump to the barge a little less intense. ;-)
Do you happen to know where does the narration by Andy Serkis come from? Is it a game? An audiobook?
