Your most hour-logged games

[Nemoide]

I don't remember exactly how much time I sank into Final Fantasy XI but it was over a week... meaning 168 hours. Not so much compared to hardcore MMO-types but I'm not a hardcore MMO-type!

I'd bet that I've spent more time with Dance Dance Revolution than any other game. At least if the entire series counts as one.

Team Fortress 2 - 612 Hours
X3: Terran Conflict - 226 Hours
X3: Albion Prelude - 88 Hours
Skyrim - 75 Hours
XCOM: Enemy Unknown - 64 Hours

Team Fortress 2 is much higher than it should be; I definitely spent a week or two idling but I still legitimately have a lot of time on that game.

Terran Conflict is entirely due to The Hub plot. There's a mission in the game that requires you to gather a ridiculous amount of resources to complete, where you need to build all your own factories to produce it because the standard NPC economy doesn't generate things nearly fast enough, and even with your own fabrication network it takes ages to do. I'd say 50 hours of that was idling waiting for the resources to be collected, as at that point I'd done all the other available plots (I think one opens up afterwards) and I was at the point that I had all the fleet I wanted and could lay waste to any sector I chose.

Albion Prelude is just a shorter game than TC to reach the same "I'm buffed up". That one I built a ship fabrication complex but bailed before I spat out the ton of fighters I planned for it; at that point it'd just be playing to play.

Dragon Quest IX - 128 hours

[BogusMeatFactory]

This is my hours put in via Raptr,

Everquest 2 - 233 Hours
Elder Scrolls: Skyrim - 177 hours
Mario Kart 8 - 152 hours
ArcheAge - 132 hours
Everquest: Landmark - 117 hours
Civilization 5 - 86 hours
Mount & Blade Warband - 81 hour

I have put more hours into other games like Morrowind and the sort, but these ones were specifically tracked by Raptr and are a definitive number for me. These are of course more recent games that I have played.

This brings a ton of memories though. Memories of completely conquering the continent in Mount & Blade Warband, the countless hours playing my friends online in Civ 5, the horrible drama involved in playing Everquest: Landmark and the head scratching 177 hours I've put into Skyrim, considering that I found the game to be mediocre overall.

I know for a fact that Waialai Golf N64 and Wave Race N64 are my (2) highest by miles - easily 200 hours each.

I don't do much that is tracked yet - so these are guesses:
Deathsmiles - 50 hours
Pro Gear - 50 hours
Zelda OoT - 45 hours
DDP DFK 1.5 - 40 hours
Dragon Blaze - 35 hours
Super Mario Sunshine - 35 hours
Super Mario 64 - 35 hours

I was thinking about this the other day. I wish I had God totals. I have no Earthly idea how many hours I spent with some games. Super Mario World, SimCity, GoldenEye, Mario 64, etc. God only knows.

[BoneSnapDeez]

I don't play MMOs and the like, so lengthier single-player RPGs would be at the top of my list. Dragon Quest VII, VIII, and IX come to mind immediately.

Oh and with all the replays it wouldn't surprise me if I have sunk more than 150 hours (each) into Final Fantasy VI, Chrono Trigger, EarthBound, and Ys I & II.

FFXI way out in front with 785 days, 23 hours, 13 minutes, and 43 seconds , no 44, 45... logged in right now

I think from there it drops down to 149 hours for Guild Wars, 130 hours for Guild Wars 2, probably similar-ish for FFXIV:ARR. Maybe a little more, but I don't feel like activating the account just to check.

WoW with about 96 hours or so.

Dragon Age Inquisition at 68 hours

I'm sure DA: Origins and some others would fit in in-between, but I didn't play that via Steam/Origin/etc.

Fallout New Vegas at 41 hours or so, Vampire the Masquerade: Bloodlines at 35ish (would be more if I finished my second playthrough).

Soo, yeah, pretty much FFXI for lots of playtime. But, that's being wound down and turned into a mobile game...so...

[SNESdrunk]

Griffey Presents MLB has to be way, wayyyy up there for me. I've finished at least 4 seasons, 162 games each, plus 8-10 playoff games. It takes ~20 minutes to play a 9 inning game, which would mean I've put something like 225 hours into that game.

[Sarge]

The largest ones I can remember recently were 99.5 hours in Xenoblade and just shy of 80 hours in Bravely Default.

I spend very little time on Steam. So my stats are a little low.

Freedom Planet
16.6 hrs on record

Valdis Story: Abyssal City
14.4 hrs on record

Ys Origin
8.9 hrs on record

Rochard
8.5 hrs on record

Escape Goat 2
8.4 hrs on record

Rex Rocket
7.0 hrs on record

Deadlight
5.5 hrs on record

Batman: Arkham Asylum GOTY Edition
5.0 hrs on record

Sacred Citadel
4.8 hrs on record

Garshasp: The Monster Slayer
3.6 hrs on record

Surprisingly, I've actually beaten all of those games. I think that time on Batman: AA is a little low, though. I highly recommend all of those except for Garshasp. That game is a low-budget GoW with a distinct Persian influence, but it's really, really janky.

I might dig through some other stats later, many of my 3DS times beat these, and I know most of my RPG times do. I'm relatively sure Xenoblade is the longest I've ever beaten, just barely eking out Dragon Warrior VII.

If I actually had to estimate which game that didn't log time I spent the most with, it's probably Tecmo Super Bowl for NES. I'm pretty sure I beat the game with every single team.
