This is the most amazing strategy game I ever played.You should try it!
There are four game modes: Skirmish, Good Campaign, Evil Campaign and Multiplayer.
In the good campaign you can train Dwarf Axethrower, Dwarf Shieldbraker from the Dwarf Hall. From the Barracks you can train Riders of Rohan and Gondor Swordsman. From the Elven Sancturary you can train Elves from two different types- Lightbearers and Archers. There is also a building where you can summon mighty Huorns-walking trees like the Ents, and Beornings- They can heal with herbs and turn into Bears. From the Stronghold-your main building, you can even call Frodo, Aragorn, Gimli, Legolas and Gandalf in battle.
In the evil campaign you have available Uruk-Hai, Orc Slasher and Orc Bowman from the buiilding called Orc Mound. From the Shadow Lair you can produce Slayers from the land of Harad and Wraiths. There is also a very important building called Troll Den. Your 2 main builidngs are the Fortress of Mordor and the Goblin Hovel. Also, there is a Beast Lair for Warg Riders And Giant Spiders.
The only disadvantage is that you cannot build walls.
You should try this game!
