Either quake 1 as a kid (netquake CA)… RTCW as a teen, or world of Warcraft as a growing adult.

Pokemon Emerald

War Thunder, approaching 10,000 hours. One day I'll get good!

I’ve yet to come close to my record of 800+ hours in Rust with any other game.

Definitely Morrowind! The Elder Scrolls III. Oh, I might actually start it back up again at some point.. Maybe one should try the Tamriel Rebuilt mod.

I dont know exactly but I have around 300 hours in every soulsborne game inkluding elden ring. Such good times.

CSGO.

Acorn Revs. can't tell you the hours, thousands would be my guess. Elite: not quite as many hours. Discovered the save file format.

Because I've been playing on and off for around decade - if not a little longer - on xbox360, I'm going to say Borderlands.

I still have a ton of content left in the game since I only had the zombie island and underdome riot DLCs until three years ago and even then still had only really focused heavily on my main account for most everything in game, leaving my playthroughs with the others far behind in the dust.

Kerbal Space Program (not 2) has around 300 hours on my steam account. I have played around equally much on another account. KSP2 is painful to see perform so badly.

Top 3:

1. Minecraft - Probably over 1000 hrs
2. Stardew Valley - 491 hrs
3. Sims 3 - 425 hrs

Near enough 3000 hours on destiny 2 and g-mod in second with 992 hours. And third is advanced warfare multiplayer woth 699

Ark: Survival Evolved. I'm at just under 1000 hours, and Rocksmith 2014 I'm at 466 hrs.

I'm at like 900 hours in Core Keeper

Evil Dead: The Game. 3k hours in the past year and still my daily goto. Probably the most underrated game of all time.

First Chivalry game was dope. Funniest pvp hack n slash ever. Can't even get mad when you die cuz the voice acting and emotes n shit was over the top hilarious. Imagine if "Were knights of the round table" from Monty python was a medieval call of duty that was it.

Chiv 2 is pretty good too but didn't get too deep honestly cuz I sunk in hundreds of hours on the first and retired.

Quake II consumed about a decade of my life. Alright, 15+ years.

Workers and Resources: Soviet Republic. 189 hours attempting to create a sustainable, green powered, communist utopia.

On Steam my top game is GTA V with like 1.1k hours, I haven't played it in over 2 years tho.

But the actual top game is probably Minecraft, tho it's hard to get an exact number.

Toram Online, 700+ hours. Not counting the time spent on the PC port though.

Minecraft. I don't know how many hours, but I bought it before nether portals were a thing and I've been playing it ever since. Sometimes a game just clicks for you.
