The convenience of Lara stumbling upon the leader of Trinity, who just happens to have grown up in a hidden village that just happens to be protecting an artifact that can remake the world was too much for me.
I never understood people's complaints about the combat in the previous two games - more combat would have added some much-needed variety to Shadow. And the game isn't even designed around the lack of combat - you spend sooo much time scavenging for resources, but the resources serve no purpose when there's no combat! If I don't need to craft more arrows or medipacks or whatever, why am I picking up all these sticks? I was literally just doing it for the sake of trophies. So much fun! Oh, and you can level up, which is great, except that most of the upgrades you can choose center around combat or resource gathering! Why is any of this stuff even in the game at this point?
