I'm on my 3rd playthrough, so yeah I like it a lot LOL gets a little boring if you do every single side mission every single time, but I like the main plot.
The story they plan on making into a movie in the future which will be amazing since (without ruining it) shows somethings that make you understand things before the LOTR movies. My mind was blown. That aside the best appeal is once you unlock alot of skills, the game is endless after you beat it. So it becomes an orc slaying game. It something I always wanted to do since seeing the guys in LOTR having a contest on who could kill the most orcs.
Shadow of Mordor, but I'm not too good. Also playing through Pokemon Omega Ruby. Anxiously waiting for DragonBall Xenoverse to come out so I can play that:]
