Play time: 16 hours 30 min (main story and most side quests, listening to most conversation)
+Good action RPG combat, severing orc limbs is fun
+Lots of well put together LotR story elements/locations for fans to enjoy
+Enough levelling and loot to keep things interesting
-Gameplay can probably get repetitive if you play more than 1-2 hours each time
-Combat system and leveling/skill tree isn't that deep for hardcore players
-Fiddly character change system
-A few glitches may crash the game
Game is great for using the Xbox 360 controller and playing on the TV from the couch.
Graphics performance R9 280X, 1080P max settings: 60 FPS (V-sync) all the time except for a few stutters when loading new textures.
If you will enjoy LotR: War in the North depends on how you're going to play the game, and if you're a fan of the LotR world. The game is best played casually a few hours at the time, If you play it that way, and you're a fan, the game will probably keep you entertained all the way through and has a lot going for it when it comes to the story and locations.
If you're not interested in the Lord of the Rings world, and come just for the action RPG, you'll probably find the game lacking, especially if you put 3-4 or more hours in to the game each go, then the game will probably feel quite repetitive.
The game tells a story of three heroes (man, dwarf, elf) indirectly helping the fellowship during the LotR story. You run in to quite a few characters from the books/movies, and visit familiar locations as Bree and Rivendell. The locations in this game generally look great, and all the characters has quite a lot to say, so the story builds up well with lots of background information available if you like to listen to conversation.
The main part of the game has you battling mostly orcs in a third person action RPG style. The combat style doesn't differ much through the game, you can select any of the three characters (but switching between them is only allowed upon clearing a section of the current chapter, or after visiting towns, and is a bit clunky), use a light or heavy attack, ranged attacks and magic/skills. You level up and unlock/improve skills and get better gear/other loot that improve stats, but the gameplay doesn't change that much. You're still hacking/shooting at orcs most of the time.
I really enjoyed the combat, and the levelling/loot was enough to keep me interested all the way through, and combat is fun. Sometimes after getting the enemy HP down enough you get a prompt to use a heavy attack for a limb severing finish that for me never got old. Just as satisfying every time.
The game has some nice boss battles as well, and every chapter has a few events that mixes things up.
At the final chapter, there was a game breaking glitch, for some reason when navigating the tunnels the game got really choppy and crashed when the frame rate got too low. Apparently a common problem, and the solution was to set the graphics to minimum and get through that section with as little on screen as possible (aiming at the floor while moving helped). When out of the tunnels, restart the game and everything is well again.
I enjoyed the game and will do a "New game+" some day.
