Most hours spent on one game?

maplestory... i spent years on that game on and off.
even more than some of my relationships LOL

it used to be good when it was hard.

they made it really easy to level now and it doesnt pose a challenge.

Minecraft, 'cause playing in that from 2012
Great game.

Ive spent 2000 hours on rocket league, that game can be hella addicting.

Well, for the most part, my highest is GMOD since I like roleplaying. Plus roleplaying as a clone trooper takes a lot of time. To the point that I didn'tsleep for a day. It was fun though

Most time I've spent on a game was like 24 hours+ on Call of Duty Advanced Warfare. I was so addicted to that game, not gonna lie.

i am doing 2500 hours on warframe and created a soloclan and never payed for stuff in the market

The game i had the most hours was gmod until i got l4d2. It's been non stop since that

I've spent more than 1000 hours earlier when Gran Turismo 4 came out xD. I really miss that game

I would think I've spent in excess of 400 hours playing GTA, but i'm not sure.

Team fortress 2, more than 1000 hours, and not playing on stopping anytime soon, unlike valve updates.

2.6k hours on Maplestory, and that's just from the time I started using the steam launcher for it. Yikes.
