I was thinking more of a single playthrough.

100+ hours combined for Smash 4 (Wii U and 3DS)

I have to think hard of non-rpg's i played...

Far cry 3 or 4, some 70 or 80 hours i guess. Doing everything in my defense ;p.

105 hours for Zelda Skyward Sword and like 100 hours for Zelda Majora's Mask in my second playthrough. I can't even imagine how much time I will spend playing Breath of the Wild...

Metroid games, 3D Marios, Smash Bros, Mario Kart, etc. are all games I play often.

Smash Bros Brawl is my most played game ever. My brothers and I played it on an almost weekly basis (And more at some points) since we bought a Wii in 2008, and we still do to this day. I expect that to change if we ever got a more modern Ninty console lol.

DS3 & Bloodborne about 70hrs each

Single playthrough would be GTA V, over 60 hours. Granted I was doing a lot of stupid shit :P

If we count replays, TLOU. I have finished the game 8 times on PS3 and 5 times on PS4 ( Hard, Crushing, Grounded, none of that easy crap) clocking who knows how many hours.

Borderlands 2 for sure, have 120+ hours played on PC version alone(playing multiple characters).

Edit: If borderlands doesn't count

All the Batman games I played on steam have 30+ hours each

A lot of people posting RPG's in this thread.

Mass Effect, Borderlands and Dark Souls are RPG's!

We live in busy times when time itself has become a luxury, so people have no time to even read the thread title apparently. :P
