Most of the Lord of the Rings fans and community out there have heard of this epic mod for the Total War Attila game which has been removed away from both Steam a long time ago and now recently on ModDB because of Warner Bros. This has to do with copyright infringement, as WarnerBrothers holds rights to making games related to both The Lord of the Rings and The Hobbit movies.
Why you may ask? most of us don't know the main reason for it since this mod is a non-commercial project and not a game that requires payment to play it. There can be all reasons for this, but one that I believe could be is that the Warner Bros are working on a total war game themself in cooperation with CA or Sega or both since there have been a few rumors about it in recent years.
If it's true or not nobody knows for sure since they haven't shared any more info after they confirmed that Warhammer III would be the last part of that series before making a new fantasy series for the Total war games. But that would explain a lot of why they are only going after this mod and not the others mods that also involve the Lord of the Rings content.
Just keep in mind that the team has only taken down the page of their mod here because they are forced to do so, but that doesn't mean the team or the mod is. The team is still working strong as ever and is still sharing this epic mod for all of us on a different website and still giving out new updates on their server here: Discord | And the Mod is here on NexusMods: Rise of Mordor | for now.
