In Mount&Blade, there is one mod to rule them all. Released in 2007, The Last Days of the Third Age is one of the most popular modifications for the Turkish indie title. With fantasy games and movies back in the limelight (Thanks Skyrim/Game of Thrones) and the mod being recently updated with bug fixes and balance tweaks, there is no better time to check this out for yourself.
Fight for Middle Earth as any faction from The Lord of the Rings universe. Each race such as orcs, elves, humans, etc. have their own racial advantages & disadvantages which combined with multiple factions incentivizes playing multiple times. A faction elimination war system has been made, as power wanes from factions they receive fewer troops and eventually can be destroyed permanently. Factions can regain strength over time or by achieving important victories. For example if Rohan and Gondor fall, Isenguard and Mordor will declare war on each other providing a longer playthrough.
