Most hours spent on one game?

I would probably say Pokemon. I haven't played the franchise in a while (got a bit stale in my opinion), but I've definitely sunk thousands of hours into it.

Most time spent was probably on Ruby/Sapphire, but also quite a bit on the ds games like Platinum.

My most spent hours on a game has to be TModloader (modded version of Terraria) sitting at around 1k+ hours lol

the most ive spent on a game was 192 hours

gmod- over 2700 hours lol

on steam? csgo. overall? even tho it's not counted anywhere, def minecraft lol

Fortnite - 5000+
CSGO - 4000+

i have like 700 hours on csgo, a lot on skyrim and ac3, also when fortnite was good i played a lot

i spent like 3k hours on csgo , i was aiming for the global elite for a while that's why i was farming this much xD

If I combine console & pc I probably have around 4k hours on MW2. This game is my childhood, so many good memories!

i spent 300 hours in gta v
