[Razek]

Most likely Runescape. I have fond memories of the older versions before it was pay to play and the whole world was pvp. I never got super serious but it was the only mmorpg I could stand to play, and my first at that. I still think it has one of the best mining/smithing/forging systems out there.

[Gen X]

I'd have to go with Counter Strike as well. Didn't play as long as some people I know but I started in 1.1 and quit around 1.6.

[jiggle]

dragonvale

[The Albatross]

GIven that CS is a mod for a pay game, I dunno if it should count. If it does, then, well, DEFINITELY Counter-Strike. I've put more time into CS than any other game ever, by far.

[LumpOfCole]

Don't laugh, guys.



TI-83 style.

[Drkirby]

Dota 2. 800 hours and counting.

[Lyphen]

Tribes: Ascend.

Close second is the Battlefield 2 demo, which I played for months.

[slackboy72]

SkiFree


Did you know you can outrun the Yeti? Amazing.

[Lucid Faia]

Don't laugh, guys. TI-83 style.

Wow. +3 respect points.

[El Sloth]

Free on PC anyways.

[angelfly]

RTCW: Enemy Territory

I was sad when QW came out since it basically killed the community.

[CarbonatedFalcon]

In terms of time, I probably put more hours into Runescape many, many years ago (though Runescape really isn't a very good game).

However Dota 2 is easily the highest quality/best F2P game I've played the most of. 46 hours in roughly two weeks of having it.

[Toma]

No Dwarf Fortress mention yet? Sad, Gaf. Sad.

[donny2112]

Tic-Tac-Toe

Edit:
Actually, as far as time, it'd probably be Spades. That can be great fun if you get the right partner. Double blind nil. :D

[snack]

Counter-Strike or TF2. Both are pretty close in terms of hours played.

[jyoung188]

I spent an embarrassing amount of time playing the Skate 3 demo before it came out. I think it had like a half an hour limit and I would just replay it over and over.

edit: I did the same for the skate 1 and 2 demos as well haha. I actually looked up youtube videos on how to glitch out of the demos and skate around in the open world until it would just glitch out or time out.

[smurfx]

zomg just installed ET and i got it to work! i'm so happy right now.

[Fjordson]

League of Legends and Counter-Strike.

[Spazznid]

halo 1 demo

+5
Their mistake was making it coop. And putting it on the best level in the game.

Also Crackdown demo.

And Battlefield Modern Combat Demo for the Xbox on Xbox live. I went a few months playing this exclusively and then bought it when it came out.

if Rift went F2P, it'd be that too.

Guild wars and GW2 don't count, do they?

[Willy Wanka]

Since people are saying CS, I'd have to say Natural Selection although it's not really free since you need to buy Half Life to play it. If that rules out NS then I would probably say Trackmania Nations Forever or Wolfenstein: Enemy Territory.

[Khold]

+5 Guild wars and GW2 don't count, do they?

Probably not, though that's the only similar type of game that I could put, 3000 hours ;-;

[gnarlycrow]

Dungeon Crawl Stone Soup

If I could only play one game it would be this.

Still have yet to take the plunge into Dwarf Fortress.

[DR2K]

Do games from buy 2 get 1 free count? If not then Angry Birds, because giving pigs the bird is fun.

[To Far Away Times]

Counter-Strike.

[VegaNine]

Sega Swirl

[boutdown]

Max Anarchy demo

[Ichabod]

I'd have to say the PS2 demo version of Flatout I got from Playstation magazine back in the day. The demo only had a few modes available--one being an awesome mode where you race off a starting platform, build up speed to hit a ramp, and eject your racer out the front window of the car, launching him through the air toward netting. What really sold the demo for my cousins and I was the rag doll physics of your racer. His body would twist and contort in the most difficult-to-watch, Faces-of-Death type poses imaginable. This dynamic soon made the game no longer about trying to get the highest vert on the take off ramp but, who could make the most grotesque, vicious looking wipeouts. The icing on the cake was when the physics engine would glitch and parts of the Racer's body would stick to the environment while the rest of him continued onward, stretching his body like silly putty. One of the handful of times in my life where I nearly passed out from laughing so hard.

[eosos]

Dota 2

[Acerac]

Team Fortress 2. Over 1000 hours and counting.

[K.Sabot]

There was an old Korean F2P mmo called R.Y.L in the states. I played that game on and off for 2 years and it was really quite amazing for its time.

[Unicorn]

[Snowden's Secret]

Minesweeper
Ragnarok Online
3DS Ambassador Program

[alfredofroylan]

Pretty much every chess game and Counter Strike.

[dmr87]

Without a doubt, Counter-Strike. It was the only game I played back in the day when it was relevant.

[Hasemo]

I'd have to go with Ragnarok Online, but if I had to pick a newer game I'd say Phantasy Star Online 2.
Played a lot of League of Legends but it was mostly because of my friends, since I never really got into MOBAs. Same with Counter Strike back in the day.

[Mupod]

If we're talking quality vs 'hours played' when defining 'most', Cave Story.

I generally run screaming from F2P games for various reasons...I mean, I loved Monday Night Combat but can't stand SMNC. I'm making an exception for MWO but I already put money into that so it won't count.

[Byronic Hero]

Fun, but hard as shit. I don't download many free games as you can see.

[WinoMcCougarstein]

I've got a lot of enjoyment out of free apps for IOS. Was Day of Defeat free? If so, might go with that.

[mantidor]

This thread has surprisingly left me without response. I've played TF2, Counter Strike, even transformice, but to say I enjoy them or they gave me valuable entertainment I don't know, they've always felt more like time wasters.

If shareware counts, it would be Heretic, I freaking loved that game, but well I did end up buying it. I guess I'm more of a single player guy.

OH I know now, Robot Unicorn Attack.

[honorless]

CTRL+F "Nethack"

Dungeon Crawl Stone Soup

Close enough!

...I'm not inclined to count games you get with something else as "free" (Minesweeper on Windows, Super Mario World with an SNES et al.) unless the "something else" is also free, though. Including those, probably Spider Solitaire or Space Cadet Pinball.

[Rubixcuba]

DOTA 2 and TF2 without a doubt.

[PaineReign]

Most likely Runescape. I have fond memories of the older versions before it was pay to play and the whole world was pvp. I never got super serious but it was the only mmorpg I could stand to play, and my first at that. I still think it has one of the best mining/smithing/forging systems out there.

Same here, the only thing that really ran on my computer. Amazing amount of stuff that was available for free.

Don't laugh, guys. TI-83 style.

:D my vote for the TI-83 would be Phoenix, played that sooo damn much. Weapon 5 was killer. Loved my TI-83 though, that is what got me into programming, so no laughing from me.

[En Ex]

TF2.

3,698 hours.

[jambo]

Free game. :p Unless you mean back before Valve made it a proper commercial game.

I mean back in the late 90s and early 00s when the mod first came out.

[Frankenstrat]

Trackmania Nations Forever. Love this game and the creativity in track design that it allowed.

[Unicorn]

Don't laugh, guys. TI-83 style.

Oh man, Space Trader on my Palm Pilot. I think it was only the demo version though, so abilities were limited, but it mattered not.

TF2. 3,698 hours.

This has to be a joke.

[Htown]

VINDICTUS!!!!!

Game's pretty good.

[ThatsMytrunks]

This year has to be Tribes Ascend, most definitely. I've logged a lot of hours and just had a blast with it.

Of all time? Hard to say, but games like Cave Story and TF2 have special places in my heart, although TF2 wasn't free for the majority of the time that I've played it.

[br0ken_shad0w]

I'm only counting games that are free since the beginning otherwise games like CS (to be fair it was free during Steam Beta), Ragnarok Online, and Nehrim would be on the list.

Only one I can think of that fit that bill for me was Gunbound (the good one, i.e. Thor's Hammer)

So many fond memories from that game, anyone remember this baby right here:


Shitty community, but damn was it addicting. Got me into Worms-style games.

[blahness]

No Dwarf Fortress mention yet? Sad, Gaf. Sad.

This is my answer. Sooo many awesome things happen in each game I play.
