Nolan North voices Eradan (the Ranger) and voices a character in Shadow of Mordor as well. Snowblind merged with Monolith after its development too so some of its developers probably worked on the new LOTR game.
War in the North was a fine game but my problem was that it was a bit too short and had potential to be more. It flirted with side quests and even providing dialogue choices but the choices weren't varied enough to forge a proper personality for the character you were playing. Of course the emphasis of the game is as a loot RPG, I think it would have done better being more like Dragon Age: Origins.
Still waiting for that LOTR RPG. The "RPG's" we do get for LOTR are all action ones where you play a set character. One thing Monolith should have took from War in the North was the looting in terms of armor. I have no quarrels with using the same upgradable weapons but it would have been nice to customize the appearance of armor. War in the North also has a more LOTR feel than Shadow of Mordor and the music is more impressive too.
