I've played all the Souls games now besides Bloodborne, out of all of them I stand at a solid 110 hours into Dark Souls 2, almost at my NG+2 which is more time than I've spent combined into the other three that I've played. I do have to say that it is incredibly easier than the others besides Demons Souls which was even easier (I had flown through the game at roughly 16 hours). Dark Souls 3 being the hardest out of the others for it's much more fast paced in my humble opinion (Pontiff Sulyvahn is my nightmare currently at level 36). Have to say I have love for all Souls type games, including Nioh which looks brilliant to me though procured my Team Ninja. Lords of the Fallen however made me feel bored, it was okay, but generally awful.
I've found mages to be awful weak in most Souls games, love hauling around the Greatsword for most of my endeavors, the Strength builds for Dark Souls 2 are brilliant, especially in PVP when you pop a Mage off the side of the map. I just really liked Dark Souls 2, I cant get enough of it, I'm so very close to getting my Platinum, just have to wreck Darklurker and get to Drangelic Castle on NG+2 and I got it, then I never have to waste time on such a good game again. Also the game was originally meant to be darker, but then they shone light upon it which really took away from the atmosphere of a Souls game.
It was okay.
