I haven't played dark souls 2 but dark souls I found to be pretty fun up until the part that everyone that dueled you was a hacker. Granted the growth mechanics were to confusing and they had serious balancing issues they liked to patch away at which usually meant nuking the everything that was op until it was pathetically weak and oping the former weak things which screws up your entire guy; if they could ever learn to fricking balance the game would have been pretty good though.
Hmm, I haven't played but a handful of games from 2012 onward but the one I would consider to be the worst would have to be DMC: Devil May Cry. I just disliked nearly every aspect of the reboot except the gameplay; for starters it's a reboot but they for some reason decided to give the new game every negative trait that has been applied to the original games. So new Dante is every bit of the womanizing, vile spewing psychopath that feminist activists have touted him as being through five games now. I loved the first three games, and have even seen the animated series that no one really knows existed and enjoyed the heck out of it. Then it's like someone decided that they would create a game that actually has all of the misogynistic ideals that the previous games were (mostly) falsely accused of having, only with a much less likeable protagonist (arguably because he actually is a misogynist now) who drops f-bombs like candy and tries way to hard to be 'cool'.
I have to admit that the gameplay was actually really good, the way you shifted weapons instantly for combos really fit well and everything felt like a further refined system of the games I enjoyed in the past; so maybe I'm being a little silly for disliking a game for it's story that never had a story of real substance to begin with. I just feel like ninja theory kind of gave people like me the finger by turning the series into exactly what it's been criticized for in the past by ignorant drones, thus making me look like the drone for defending them in the past. Oh well, it's one of like 3 games I've played from that period so it's all I've got to hate.
