I'm no casual when it comes to Dark Souls. I've gotten all the achievements on Ds1R Nd DS3 and I'm maybe 2 or 3 off for DS1 vanilla.
Having put multiple playthroughs and hundreds of hours into those games, and having owned both DS2 and DS2SoTFS I would have put the same amount of time or effort in. But sadly. This game has always been my bane. Much as I love it (and have nary a thing to be said bad, honestly), it has always been the one I've never put any effort into. That changed.

Now here I am, 6 achievements away from 100%, wrapping up the last remnants of NG and almost ready to move on to NG

I fell in love with this game in a way I didn't know I could by actually following all the storylines and quests.
