The Forces of Darkness are the fighting Uruk-hai of Isengard, and Mordor's orc hordes, bolstered by Haradrim, Mûmakil and Trolls. Four factions on two sides wage the War of the Ring: Representing the Free Peoples are the horse-lords of Rohan, and Gondor with its forges and battlements. The only resource are the nebulous 'resources,' which are produced inexhaustibly in dedicated buildings. Plots range from farmhouses to full-fledged castles, with different slot arrangements and available buildings, and plots can be purchased when they're in the sole presence of a side's forces. In The Battle for Middle-earth, buildings may only be constructed on the building slots of predefined plots.
Warring factions gather resources, then use them to construct military bases and armies on-site. The Battle for Middle-earth is a real-time strategy game.
