Middle-earth: Shadow of Mordor

Shadow of Mordor is a decent game that is ruined by one fatal flaw: It's too easy.

As advertised everywhere, a big part of the game is the "Nemesis System", where orcs that kill you become more powerful and rise in the ranks of Sauron's army. This works very well at the beginning of the game, forcing you to actually plan your encounters with your powerful enemies in order to defeat them. Unfortunately, over the course of the game you gain many new powers and abilities - but the orcs don't. At about the halfway point of the game, you've become a nearly invincible badass that can slaughter dozens of enemies in one go. This also means that there is no challenge left in the game and in turn it becomes rather dull. The boring environments and unengaging story don't help it either.
