you had to do some side quests and stuff perhaps to level up a bit if the content was too difficult. By the end of the game you felt like a demi-God and were way more powerful than your opponents -- at least that's where my char ended. I died an awful lot at the beginning too -- the sense of power and progression in the game - as you acquired additional passive and active skills was epic. I was able to kill all the end bosses quite easily, even in bunches by end game. It's actually enjoyable to become overpowered by end game and just destroy enemies that were difficult before.
Hmm interesting. Ya I think I only did very few sidequests, and I didn't know I needed those to upgrade my skill set.
I see with this new Shadow of War, they give you the ability to change difficulties. So that sounds encouraging. I don't like challenging games, I prefer to play on easy and enjoy it.
