Most hours spent on one game?

CSGO 2,500 hours yeah i don't know what i do with life heh

Probably world of Warcraft. Im at hundreds of days played (for those not familiar that would be hundreds of days if I never slept and just played straight)on my main and god only knows everything combined. I long ago stopped using /played. I just dont wanna know. It is over 10 years, but still, dont wanna know.

Longest non-mmo is Skyrim. Ive played it at least 3-4 full times (with short bursts here and there). The full play throughs are all 200+ hours each.

Even though I dont play anymore, Its probably World of Warcraft with 10k+ hours atleast.

3000 hours playing Counter strike in general

Probably Minecraft with at very least 3k.
After that Halo 4 with around 400, Binding of Isaac + Rebirth with 300, Dark Souls 1 with 200

Probably either MW2 back in the day or Skate 3

It might be GTAO with around 500 hours played.
