Most hours spent on one game?

I have over 2k hours in CSGO and thats basically it

2k on csgo, 1k on Pes 2021

Gmod, lol, over 6k hours. Actually I'd like to spend that time on other games.

PROBABLY LIKE 500 ON NBA 2k

200+ on FM 13 I think, maybe 14

Definitely sub one thousand, maybe 300 or so

Well, I spent the most hours on Garry's Mod.

over 3000 hours on an indie game and I think over thousands on Minecraft lol

3,980.7 hours in Arma 3. I've literally been playing this game all the time for the last like 5 years. If you like more realistic types of shooter games, Arma 3 is literally just a combat sim. Although I must admit, as of recently I've kind of gotten tired of playing. Not playing the game, but tired of the community. I like to play the game in a very specific way, and it's really rough finding any communities that have a few of the aspects I like to play in, let alone all of them.

Uncountable number on a stupid Gacha phone game, most for a pc game is 250+ in oblivion back in the day
