Basically a polished mix of Batman Arkham and Assassin's Creed, taking the better elements of both of its inspirations and having the nemesis system as what sets it apart. Combat and parkour both feel satisfying to play with, though I'd say the Nemesis system doesn't feel as fleshed out as it could have been, it's cool that named enemies remember you and you can form a bit of a rivalry with them, but this doesn't amount to much aside from their one-liners when they meet you changing. Not to mention the outcome of these fights is always one of the following:

You kill them.
You get killed by them.
You run away.
They run away.

I imagine the sequel to this game probably does more with this system, which is why I'll be getting it later. Another thing I didn't like is how anti-climactic the last couple of missions were, even though there's this huge build-up leading to them and the final boss. But yeah, those missteps aside, I do consider Shadow of Mordor to be a good game, it has a decent story, which despite never having consumed anything LotR-related I was still able to understand and get invested in, great visuals and atmosphere, as well as an overall satisfying gameplay.
