Just like the thread title asks. What would it be yours and how many hours have you spent in it?

Bonus question: do you feel you invested hours in it looking back, or that you wasted them?

Mine: Fallout 3, over 800 hours of gameplay in a saved file.

For consoles that would be Mario Kart64, Final Fantasy X and Final Fantasy 7.
For X and 7 probably around 250-300 hours.

On Pc.. Wow, Civ2, Usm2. Countless hours...

Dragon Age inquisition. Got 40 hours in one play through but wanted to reroll as a warrior/reaver. So I did and played another 60 hours. I've never put 100 hours into anything. I've played ME 3 times but each was about 23-25 hours.

The game that should not be spoken...

Heroez of Might & Magic III although my fav is II

Dota and Heroes of Newerth, more than 2K

That game is the absolute BEEEEST! I'm still playing that with a friend to this day xD

Dota 2. Currently at 2870 hours.

What, of all-time?

Either Rollercoaster Tycoon 2 or SimCity 4. It's a shame they don't keep time but it's got to be thousands of hours, up to ten-thousand maybe even. Have been playing them consistently since release 13 years ago. The only other contender for the title would be Anno 1602, but that one's definitely third place.

And no, none of those hours are wasted. Maybe a couple on SimCity when it crashed and I forgot to save.

One of them is GTA V. On PS3 between all characters, I got 99h 55m 11s. Now, on GTA Online, with all my progress transferred from PS3 to PS4, I made 1188h 40m 44s.

One game I'd love to know for certain is MGS Peace Walker, where I got approximately 200 hours plus another 400 hours with a deleted save file.

The next one has to be Mass Effect 3 multiplayer where I made 253h 12m 30s.
