I guess I can’t know for sure, but I’d say it has to be Minecraft. I wish there was a way to see the hours I’ve spent in the Java Edition of the game. If it’s not Minecraft though, my second guess would be Rocket League. When I add up the hours across the platforms I’ve played on, it comes out on top by a small margin.

That would be:

Dota 2

Warframe

Path of Exile

Skyrim

Mass Effect 3

Dragon Age: Origins

Apex Legends

Probably Minecraft. But I haven’t spent an insignificant amount of time in Garry’s Mod either.

For a single game it’s Factorio. Steam has me at around 1600 hours.

For a series it’s gotta be Civilization. I’ve been playing since I was in fifth grade. I’d go over to my friend’s house when he wasn’t home to play Civ I. I’d spend entire weekends in college playing Civ II and III. I had to have my GF hide my Civ V disk so I wouldn’t miss deadlines. And now I’m on a full playthrough of all the new civs in the latest DLC.

MMOs were always my thing. I’m almost glad I don’t know exactly how much time I buried into World of Warcraft back in the day. I haven’t touched it in 15 years and it’s probably still in the lead. I play a fair bit of FFXIV these days but not like I did WoW. Asheron’s Call 2 was a big part of my life for a long time but it’s been offline most of my life.

Among recent games I’ve actively played for years, Rocket League and Minecraft are for sure at the top.

I like games I can just pause and walk away from for a bit. Or just play while watching videos. So the hour counts are never really accurate. But I can safely assume in the past few years its Rimworld. It’s my game I can play while doing other stuff. But if I crank up the speed it’s engaging enough to focus on if I want to.

Lifetime totals it may be Minecraft though, I usually go back to it every few years. The urge comes and goes.

I’ve been playing & modding Neverwinter Nights since 2005.
