Your 100 + hour single player games!

[Vigormortis]

I'm sure there were some that I logged that many hours in as a kid, but I'm not sure of which.
That said, I am sure I've logged at least 100 hours in each of the following:

Half-Life
Half-Life 2
MechWarrior 2
MechWarrior 3
MechCommander 2
MechAssault 2
Sins of a Solar Empire
Starcraft
Homeworld
Banjo Kazooie
Banjo Tooie
Perfect Dark
Goldeneye
Metroid Prime

Primarily given that I still play most or all of these games from time to time. So, if only for that, I've probably logged that many hours in them.

Some games were omitted, simply because they might have been considered too "multi-player" to count towards the OPs criteria.
(Sins of a Solar Empire stays on there simply because I've played the hell out of it both with friends and by myself)

 

[Maveroid]

The only one I can think of is Devil May Cry 4 which said that I played for 113 hours

 

[SoloStoffe]

I'm sure I've passed it on plenty of games, although I don't recall which ones. The one I'm sure I've passed it on however is Skyrim (144h as of right now).

 

[The Human Torch]

World of Warcraft, Pokemon Black...that's about it though. A game needs to be REALLY enjoyable for me to play it that much.

 

[GodofDisaster]

The only games that I can think of are.

Resident Evil 4

Resident Evil 2

Pokemon Plantium

Pokemon Blue

Pokemon Black with over 500+ hours and counting.

I'm sure there's more but I can't remember.

 

[thetruefallen]

I know i have put way more time than was healthy into some games, in some cases way more than 1000+ hours. Not even sure I can remeber them all now, i know im going to forget one or two...

Pokemon: Red; Blue; Yellow; Gold; Silver; Dimond; Emerald; White; Black;
Diablo 2 (got to be at least 3000+ hours the only game i played pretty much in high school)
Oblivion
Skyrim
Fallout 3
Fallout: New Vegas
Supreme Commander 2
Minecraft
Mass Effect 2
Civilization 5
Tony Hawk Pro Skater 2
Dawn of War
Red Faction (Finished it over 15 times over one month when i didn't have ANY spare cash or games at all.)
Grand Theft Auto 2
Grand Thrft Auto: Vice City
Grand Theft Auto: San Andreas
Titans Quest
Defensive Grid
Saints Row 2
Sims 2
Sim City 2000

Thats about all i can remember off the top of my head. Oh wait! I also deal Blackjack for 8 hours a day full time, surely that has to count aswell?

EDIT:
Half-life
Half-life 2
Mechwarrior 4
Solitare (according to my pc i have play 104 hours of that game since 07)
Plants vs Zombies
Peggle
Zuma
Sodoku (on my iphone, still counts)

 

[V TheSystem V]

Super Smash Bros Melee and Brawl (doing a lot of stuff single player. No joke).
Pokemon Silver.

I got unhealthily obsessed with getting trophies and stickers...

 

[everythingbeeps]

Skyrim's the only game I've put 100 hours into in one playthrough.

I've played New Vegas and Fallout 3 a couple times each, but no single playthrough topped 100.

And aside from NES and SNES games that I'd play for hours on end, I think that's probably it.

 

[MiriaJiyuu]

I dont really play multiplayer, so going down my steam list, and my game library after that

Mass Effect 2
Minecraft
GTA: San Andreas
Saints Row 2
Saints Row The Third
Splinter Cell: Conviction
Assassin's Creed II
Assassin's Creed Brotherhood

Older games to name a few
Sly 3
every Ratchet and clank on the PS2 save size matters
every Jak and daxter game

 

[Neko Pounce]

About 129 hours spent on Mirrors edge getting speed runs maximized on every level and trial.

 

[DasDestroyer]

Not sure exactly how many hours for them, but I can't be arsed to check.
Fallout 3
Fallout New Vegas
Minecraft(I mostly play SP)
Terraria(see Minecraft)
Persona 3 Portable
Age of Empires 2
Skyrim
Ratchet: Deadlocked
Marvel Nemesis: Rise of the Imperfects
Darkwatch
GTA San Andreas
The Third Birthday

That's about it from the top of my head.

 

[Mr_Universal]

skyrim.
oblivion .
fallout 3.
fallout new vegas.

and,Super Mario Bros...at least I would think so...

 

[Farson89]

Pokemon Yellow
Pokemon Gold
The Elder Scrolls IV: Oblivion
Rome: Total War
Medieval: Total War
Medieval: Total War 2
Empire: Total War
Age of Empires 2
Dragon Quest VIII

I think that's all of them.

 

[Wolfram23]

Skyrim and Demon's Souls are the only 2 over 100 that I can think of.

Gran Turismo 5 might be close, I know for sure I'm almost there in FO3, like 80ish.

Other than that, I don't can't think of any. Most games are 50 hours or less.

 

[Nigh Invulnerable]

100 or so in Pokemon Silver
100+ in San Andreas on PS2
500 in Fallout 3 on 360
800+ in TF2

I think you missed the part about single player with that one.

Oh I'm soooooo sorry I made a mistake, dearie me it must have hurt you to read that I put a multiplayer game in on accident.

How about next time you just ignore it like the rest of the community.

Wow. No need to get snarky, dude. Just saying, TF2 is cool, but clearly not much for single player.

 

[clint945]

I've honestly no idea since i'm old-school and most of my games are not linked to steam and the like, so i don't have an accurate measure.
But i'll list a few of the ones that i think should be over 100 hours:

Sim city 3000
Silver
Dungeon Keeper 1&2
Daggerfall, Morrowind, Oblivion, (NOT skyrim yet actually, been doing other things)
Fallout 3
Age of Empires 1,2
Empire Earth 1
Settlers 3
FF 3,7,9,10
Homeworld 1, 2, Cataclysm
Lords of Magic
Lords of the Realm 1,2
System shock 2
Deus Ex (and Human Revolution)
Gears of War 1,2,3 (Single player only, with more time for multiplayer but that doesn't count)
X3 Terran Conflict
Freelancer (easily over 200-300 hours, i've completed 7 playthroughs)
Freespace 1 (Collected all medals and full rank xD)
Tachyon The Fringe
Neverwinter Nights 1
Dungeon Siege 1
GTA 1
Vampire: The Masquerade
Assassins Creed 1
Garrysmod (technically multiplayer but i've spent over 100 hours building on singeplayer)
Gothic 1,2,3,4 (I love this series more than Elder Scrolls.)
Risen (Aka, Gothic 1 Mk2)
Sword of the stars 1
Space Empires 4
Pax Imperia (probably logged about 500+ hours on this game...)


There's probably a lot more... but i can't think without my game collection infront of me.

 

[T0MLAD]

418 hours football manager 2009
548 hours football manager 2010
498 hours football manager 2011

[omicron1]

Minecraft, Oblivion, NetHack, and that's about it. Normally I only play through games once.

On the other hand, I've spent many hundreds of hours programming and testing my current project (a mashup of MInecraft, Oblivion, and Nethack... Seriously.), so I don't game as hard as most people. Still passionate about it, though.

 

[Plurralbles]

Rome Total War
--Rome Total War Roma Surrectum Mod
Oblivion
Skyrim

I don't have the exact times for any of these games.
