The Third Age: Total War mod has released a preview of the redeveloped Eriador units and the implementation of the new Arnor faction. The development idea behind the project is to have Arnor’s units replace Eriador’s once the player has reached certain benchmarks. A description of Eriador from the official thread reads:
Eriador isn’t a kingdom, it isn’t a state, it’s just a region encompassing the lands west of the River Greyflood to the River Lune. Because of this there was no central authority. The small villages and towns (like Bree) were completely independent. The northern lands, once prime Arnorian territory, has been completely abandoned except for a few Dunedain camps. While rebels might make for satisfactory filler for the area; a full fledge faction (properly implemented) can offer the player the opportunity for unique challenges.
The rest of the release can be read here.
