What is the longest video game you ever played?

My longest played videogame is monster hunter freedom unite, played it for about 750+hours. I only played that game an hour or two a day, but I played it for about two years. It was so fun that i didn't even buy another game. My second longest played was metal gear solid portabl eops plus. Single player was fun and online was addicting. My psp broke so I don't play those anymore though :(

WoW. Probably over 1,000 hours.

GTA series around 200 hours in all games

Fallout 3 and New Vegas close to 500 hours

WoW by far.

Probably 300+ in Morrowind.

1.) 300+ in Disgaea 3

2.) 200-300 in Disgaea 2

3.) 78 hours and counting in Persona 4

Probably something along the lines of WoW or RuneScape back when I used to play either.

Could possibly be a Final Fantasy game.

Super Smash Bros Melee: Beating the game 100% and playing multiplayer with friends probably adds up to like 500 hours

Xenoblade: Took me 100 hours to beat the story and there's still more stuff I want to do

Pokemon Red-Ruby: I replayed Red many times and put about 250 hours into Ruby and about 200 in Gold

Advance Wars Dual Strike: I've clocked in about 150 hours

In terms of total time played, Star Ocean: Till the End of Time at 2000+hours, but that's been over many playthroughs.

In terms of a single campaign to 100% the game, Gran Turismo 4. I've never been able to 100% it after starting a new file, but have sunk 100-200 hrs into each file.

If considering games with a plot and definite end, probably Persona 3. 1st run through was about 110hrs long.

That's a tough one. Single player wise, I think either Pokemon, Fallout 3, or the Grand Theft Auto games. But I've logged in hundreds of hours into the multiplayer for the Halo games, Super Smash Bros, and Mario Kart.

I've 1000+ hours in each of them

Journey

GTA 4

Gears of War 2. Spent so much time on that.

Fallout 3 - a single playthrough can take me over 100 hours easily.

The longest time I've spent for a videogame? Chrono Trigger, for sure. I still remember going through more than 80+ hours of gameplay without any sleep when it first came out. I was that determined to get everything possible, including all the endings.

Flight Simulator X. I have at least one free flight mission daily since I bought it back in January 2007 with no signs of quitting any time soon.

I'm really not sure. I think Team Fortress 2.

World of Warcraft or the Sims I suppose since both technically have no ending. Although I did play Sons of Liberty all in one session once. That seemed like an eternity to me...
