It must be RuneScape. Probably followed very distantly by Pokemon, Diablo II, Skyrim, and the original COD MW2 to name a few

War Thunder, by far. Been playing it for between 1-5 hours every day for past 10 years.

Steam seems to think I've played chasm for 444 hours, but it must have been left on lol. Steam has me at 150-ish on Hitman 2, one of the nba 2ks, Witcher 3, and Elden ring.

Not Steam, original destiny was like 800.

Dead by daylight, by now 3.8k hrs.

How is Surviving Mars? I got it on a steam sale but haven't played it yet. Got deep into Cities Skylines by the same company so thought it was worth a download.

CSGO and RuneScape (now osrs).

My top 3 are Battlefield 5 at almost 1500 Battlefield 1 at a bit over 1300 7 Days to Die at a bit over 1000

Battlefield 4. Was there from the buggy as shit release on the PS4 back in 2013. A little over 600 hours. Some of my best gaming memories.

Lord of the Rings Online - MMO WoW Monster Hunter World

Historically? Hard to say

I had close to a thousand hours in Modern Warfare 3 and Black Ops II back in the day, but i was in middle school and gaming was the main way me and my friends hung out outside of school

If minecraft accounts tracked playtime id be at least 1k there over the years if not much more

On steam I have close to 600 in rocket league, havent played it in a while but thats the most played that i can verify

Breath of the wild for me. The switch only counts up to 500 hrs and I know I’m probably double that. 100% the game on master mode with very very little help from guides. I just love that game man. TOTK is great too but my heart is still with BOTW

1. Conan Exiles - pity tencent monetized it, I had well over 1000 hours and had no intents on quiting until they riddled a 3 year old game with microtransactions.
2. Ark - Dinosaurs are fun. Nuff said. Mixed feelings on the upcoming news. Remastered and the delays with 2 have me debating different games.
3. Eco - was a great community game. It's dying out a lot due to the slow update process these last two years. Water updates were something I was hyped for 2 years now, and it still isn't out yet. <.<.

I've sunk a lot of hours into both guild wars 2 & Warframe. over 5000 apiece, iirc. but they're both MMOs, so that's not that unusual.

the standout for me in grim dawn. I'm at over 2500 hours, which seems just a massive amount for a game that's not an MMO or even an open ended, open world game like skyrim or fallout.

Ultima Online.. so good.

Top 3:

• The Elder Scrolls IV: Oblivion
• The Elder Scrolls IV: Skyrim
• Pokémon (combined)

Well Steam says I have 10,500 hours in Dota 2, but if I check the total combined time of every match I've played in the past decade+ it's actually only... 4500 hours.

Fuck me that's a lot of time and electricity wasted.

I played WoW religiously from vanilla until Legion with very few breaks. I think I had over 3 years in game time on my main when I quit, with a few more years spread between alts.

Next would be Path of Exile, 3000 hours and counting.

After that, probably Dota 2 at 1200 hours

I'll have to check later, but no doubt it's Factorio. I believe I'm near to or over 2k hours, over nearly 10 years of owning it.

Ultima IV. I was mapping out the full world on graph paper, then my cat pissed all over it. :(

Next is probably Destiny/Destiny 2. Multiple thousands of hours there.

Soulcalibur VI and Nioh were two games i spend 500+ hours on. But if i go more back in time it's probably something like Guildwars or Elsword.

I have about 4000 hours in CS:GO with most of my time being in community servers. About 1500 hours spent matchmaking, the rest split between surf and KZ.

Borderlands 2, combined across systems I have over 1k hours

Its either champions online or star trek online. Played them both for years and by and large did at least minimum grind on the events.

MLB The Show and Star Wars Battlefront 2 (2018, co-op with my friends). I play them both every Friday night and have hundreds of hours in each.

Over 2k in Rust and Mordhau, but probably Morrowind. I sank some serious time into that on Xbox as a kid.

My top 5 would be:

World of Warcraft (easily over 10k hours, been playing since release)
EVE Online
Crusader Kings
Stellaris
Blood Bowl

World of Warcraft. Estimate around 15 000 hours.

League of Legends. A tough one to estimate. Maybe around 3 000.

Then its Diablo 2 or Warcraft 3. No idea which one is left outside of my top 3 tbh.

According to Steam it’s Left4Dead. That said, Steam only began tracking use in 2009. Not only do I expect my Left4Dead hours to be much higher as I played that mainly at launch in 2008, but I also think that game would be a distant second to Counterstrike Source which I played heavily around release while I was in university.

Probably Heroes of Might and Magic III.

honestly? Probably skyrim. Divided up between multiple systems, of course

10,000 hours in DAoC. The best MMO PvP to date. Objectively.

Civ VI and ARK: Survival Evolved. So many hours on those, they’re addicting!

Counter-Strike:Global Offensive. 1800 hours or so. Picking it up again the past few days and god damn am I trash after having not played regularly for years.

Fuck. It could be Wario Land or Donkey Kong Country 2 (a bit later, 1996?) for me. Been playing them almost constantly since 1994 along with Mario 1-3. This gets even more fucked when you throw in all the ports, randomizers etc.

For actual hard numbers (roughly), it's Xenoblade for me.

1. Played once on the Wii when it came out here in the UK in 2011. 107hrs.
2. Played it again through on the Wii. This was around the same, savefile says 142 hrs.
3. Played through it on Dolphin. Probably 80hrs or so, I don't have the numbers on this. Throw another 100 hours on.
4. Played through it to 100% on the New 3DS port, twice. This was probably another 200+ hrs.
5. Definitive edition. Played through once on the Switch to 100% (this took 97 hrs) then twice again on Yuzu in 4k. 150 hrs so far on Yuzu (just got to Valak Mountain in this current playthrough)

Don't even get me started on X, 2 and 3. but well worth it.

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.
