Binding of Isaac Rebirth (I think, it doesn't track time, but I got the platinum)
Hyperdimension Neptunia Victory 2
Not sure what the third would be. I don't really keep track of time, I'd actually prefer not to know
If handhelds count:
Pokemon Y
Animal Crossing
Probably some Vita RPG
After that the number of hours played is much less. #3 might be Shadow of Mordor at only 30 hours. I have played about 110 hours of Dark Souls 1 this year though if that counts.
None of these games keep count so I'm just guessing here. LoL is definitely #1 but I'm not sure about the Hearthstone/Bloodborne order. The Last of Us is also pretty close and it might overtake Bloodborne soon since I've been playing the multiplayer quite a lot recently.
Steep steep drop off after that.
Unless dwarf fortress still counts.
I just keep coming back for more, the way you leave an impact history in the adventure mode is amazing.
Several of my characters that managed to survive long enough to be formidable are durectly responsible for massive events, including wars and changes in eras.
This thread made me realize I don't really play games very long.
#1 Smash - 49 Hours.
#2 The Witcher 3 - 27 Hours
#3 Pillars of Eternity - 25 Hours
#4 Bloodborne - 25 Hours
#5 Final Fantasy Type 0 - 21 Hours
#6 Resident Evil Revlations 2 - 21 Hours
As you can tell I really don't play games long. I hit it and quit it. Smash is only so high up because it gets a lot of time played with friends when they come over. I don't play it outside of that.
