Far Cry 4 (2014)

Best: Riding An Elephant: Far Cry 4 (which as you can tell now is not the fourth game in the series) switched things up and was set in the fictional Himalayan country of Kyrat, complete with snowy mountains and elephants. And riding one of these massive pachyderms is still one of my favorite bits from a pretty solid entry in the series.
Worst: Bad Binary Choices: Throughout the course of the main campaign you have to make some choices about how to help lead this revolution. The problem is these choices tend to be mostly binary options and both options tend to suck. I get that Ubisoft wanted to make things morally grey and all that. But it really just makes it hard to care about anything when you realize you are going to have to make bad calls throughout the story.
