I had a very same thing not so long ago, OP. I think you're just fed up with games. You need some rest. But after you get it, the desire will return. I had this once. I've deleted every single game on my PC and started to watch movies at evening. After 2 weeks I've downloaded Overwatch, because one of my friends recommended it to me. And I have played Overwatch since then almost every day.
As the OP, I have to say that for me things changed a bit over the past two years plus. My "no interest in games" funk lasted another six or seven months after my first post, meaning that for pretty much all of 2018 I barely played anything other than the odd hour here or there in an indie game as I tried to see if they would spark anything.
That Christmas, though, I got an UW monitor (about as much for work as for trying to rekindle gaming interest) and Wolfenstein, Tomb Raider and Shadow of War kicked off a renewed interest. I went back and finished DSIII and all the DLC (and NG+) the next year.
I am kind of feeling a lull again now, after going as far through Nioh's NG+ cycles as I could manage before it became a bit too grindy for my tastes. Been looking through my libraries and wishlists and finding no motivation right now.
Perhaps interesting that it was putting lots of hours into DSIII (and having been banging my head against what was at that time a brick wall in Sister Friede) that preceded my previous lull and now it's Nioh (and the slightly softer but still tangible wall of the endgame of Way of the Wise and the horribly buffed bosses that start cropping up). Perhaps a bit of burn-out from the relatively more demanding Souls-like games, who knows.
Quite happy to have a break for a while this time. I still need to watch series four of The Expanse for one thing...
