This is a modification for the Battle for Middle Earth 1 & 2 PC Video game, which for BFME 2 will add Rohan Back as a separate faction and will enhance the current factions to give you a "lore-wise" battle-field. And in BFME 1 enhance the atmosphere by finishing the unfinished goodies and of course adding more to the game-play and so on :P.
A quick glance at a Gondor & Elves v.s. Isengard Skirmish ! Elves barely helped though XD
