Your most replayed video games?

Final Fantasy VII

If Dota 2 doesn't count, and I think it shouldn't, then it's Pokemon Crystal for me. I don't really remember how many time, but I played it as a kid, the Japanese version. Yeah I don't know how the **** I completed it that time(complete as in beat Red the final boss, not collect all the pokemon), well I didn't know English either, so language doesn't really matter. And then as I grew older a bit, learned English and replayed Crystal and other Pokemon games, but I must say Crystal is the best version, huge maps, huge content,... Every once in a while, I would pick it up, beat the whole game, rinse and repeat.
I never have a chance to touch a real GBA though, the emulator on PC run very fast so it doesn't take that much time. If I played on a real GBA then I don't think I could play that much.

Skyrim ;)

Tomba! 2
Too many fucking times when I was young.

Ape escape 3
played it like 4 times (i think)

The Elder Scrolls V: Skyrim...

Final Fantasy IX
Metal Slug Series

XCOM:EW
Saints Row 3
Tomb raider (2012)
Mega man X (SNES)
Final Fantasy tactics

Star Wars: Kotor

I rarely play again a game I've finished. The few I can recall are Mafia I (which I consider as the best game I've ever played), COD Modern Warfare, Prince of Persia The Two Thrones and NFS Most Wanted (the original one).

Dark Souls

Super Mario Bros

Skyrim
Fallout: New Vegas
Fallout 3
Mass Effect
Half Life
XCOM: Enemy Unknown
Deus Ex: Human Revolution
Assassin's Creed 1, 2, Brotherhood
Splinter Cell 1,2,3
Mafia: The City of Lost Heaven

Mafia, GTA: VC, GTA: SA, TES3: Morrowind finished ~5 times.

deus ex: hr - 4 times
dishonored - 4 times
half-life 2 - 4 times
hitman absolution - 3 times
borderlands 2 - 3 times
batman: ac - 2 times
portal 2 - 2 times
mirror's edge - 2 times

that's all I can remember right now, these are of course not right after I finish, mostly I repeated them after couple of months, since they are all masterpieces for me, I'd like to play them occasionally..

Mafia II - More than 10 times(probably the best game I have ever played)
Devil May Cry 4 - 6 times
....I think thats it :D
If you haven't played these games I recommend you to play them ;)

Nowdays i dont replay games too much, back then i was hooked with C&C Generals, Zeus Master of Olympus and UT2004, somehow these games was the perfect games to pass my time with joy.

Games i completed atleast twice i remember:
Half-Life 2
Bioshock
Bioshock Infinite
Batman Arkham City
Borderlands 2
Call of Duty 4
Deus Ex Human Revolution
Portal 1, 2
Quake
Tomb Raider 2013

The Stanley Parable :P

Crash Team Racing

Day of the Tentacle
The Legend of Zelda: Link’s Awakening

Devil May Cry 3 and Resident Evil 4 surely take the place for me.

Jedi Knight: Jedi Academy. I had to have played that through at least 5-6 times.
Torchlight 2 I played to NG+++ on 3 different heroes.
Most other games I will usually play through once then maybe dust it off a good while later if I get bored.

Baldur's Gate 2: my estimate is about 2000 hours in it, so at least 20 times I guess. maybe more, maybe less. I have a lot of stopped characters near the Friendly Arm in part (usually playing Trilogy mod).
Deus Ex: Easily more than 30. I think I have reached the point where I actually know the location of all NPCs, hidden items, and routes by heart now. All I lack is the speedrun strats/glitches, for some reason I was never interested in it, even though I love watching speedruns.
Super Mario Bros 3: 100 times? More? Never was actually good at it, it was just my only game with UMK3 on my SNES for 4 years.

If skirmish play would count, I would also say Red Alert 2: Yuri's Revenge (strangely vanilla, not modded) and Age of Empires 2. I have sinked more than a thousand hours into both.

It's probably World of Goo for me. And Bastion as a runner-up.

Either Fallout New Vegas or GTA San Andreas. Don't really replay games much

Final Fantasy 8. I have over 800 hours on Steam, and countless hours before that. :p I just love that junction/refine system.
And Skyrim, I think this is my fourth playthrough.
