Great campaign! Goes well with movie!
The best thing I liked about this game was how you each and every one of your men can gain levels and with each level, your character gets better armor and weapons. The trolls (evil) start to wear face paint, have more health, and are much more powerful.
Also, you can have any of the heros that you see in the movie. You can be anyone from smeagul to a dragon rider. With this span of heroes, you can have many different powers at your disposal.
They did copy the godly powers from Age of Mythology, where you can have a selection of godly powers to use whenever you want to. You can use your eye to spy on their base or make your resource rate increase for a certain amount of time. This powers help a lot when you play online and need a boost to help you out.
My only problem with this game is the lack of variety. One of the things that I love about warcraft 3 is how you can play different game types, very much unlike LOTR Battle for Middle Earth, where all you can do is fight. Also, the online play is extremely hard because if one person in your server has a messed up firewall it will completely close the server and it does not tell which one of you has the messed up firewall. Other than this, this game is incredible and you should definately try it out.
