Contested Sequel: 2011 and 2013 are the closest in terms of story mode and gameplay so the comparison is natural. Which was better is up for debate. 2011 is generally thought of either too over the top and failed at being engaging with its story, or was So Bad, It's Good for the same reasons. 2013 either smoothed out those problems and streamlined the plot, or is It's Easy, so It Sucks because of the massive increase in medkits and ammo pick ups.
Crowning Moment of Awesome: Say what you will about them not being hunting games in the slightest, the boss fights in 2011 and 2013 especially will make you feel like a badass.
