Two new movies on 3D Gamers have caught my eye, whether they are actually unseen videos I dont know as they've not finished downloading for me yet ! The first game is the strategy game 'The Lord of the Rings: The Battle for Middle-Earth' <takes breath> which I've heard is promising but not really followed the development of so I'm interested to see this video. The second game is World of Warcraft, the highly anticipated MMORPG.

** update **
Now that I've seen the LoTR video all I can say is you gotta download it right now! The WoW video shows over 5 minutes of ingame footage and is well worth checking out as well but right now its LoTR that has me itching to play it.
