For certain my most played games in 2017 are:
1. PS4 - EDF 4.1 Shadow Of New Despair + 2 dlc packs - 503 hours
2. Vita - Hyperdimension Neptunia: Re;Birth 1 + dlc - 122 hours
3. Vita - Dragon's Crown - Around 80-90 hours
4. PS3 - Yakuza 5 - Around 60 hours + another 60 in 2016
5. PS3 - Dishonored + 2 dlc packs - estimate - around 50 hours
6. PS3 - EDF 2025 + 1 dlc pack - estimate - around 40 hours + another 70 in 2016
7. PS4 - Hitman - estimate - Around 30 hours
8. PS3 - Hotline:Miami estimate - Around 30 hours
9. PS4 - Everybody's Gone To The Rapture - estimate - around 25 hours
Those are the big ones. 1, 2, 3, and 5 have in game clocks. I think Dragon's Crown has a game clock, but my estimate is solid.
