Is there a way to delete play time on steam?

I often forget games open, specially after ALT + tabbing.

I don't think you can "erase" time played. Well, talk to steam support if this bothers you.

About 103 of my 105 hours of New Vegas were from this sort of thing.

@OP Why don't you use the save game timestamps to tell you how long it takes you to beat the games? A lot of game saves tell you how long you've played the specific save. I understand that maybe its not even half the number of games that tell stuff like this, but in case this happens to a game that does track play-time per save, in the future.

AFAIK, no there isn't

Only thing you can do is have the games removed from your Steam account. But then, if you ever activate them again, they'll be back to the saved playtime (I think), so you'll have to live with not having them on your Steam account.

Oh, so you're kinda anal... Now, tell me what would you do if your game showed over 1 MILLION of hours of playtime? Don't think it's possible?
Have a look: http://steamcommunity.com/id/maxtdk/games/
Now look for "Half-Life 2: Episode Two" and the overall time on record

Try turning ya computer off everynight to save power....Then atleast that;d stop ur game running:P

use you cellphone chronometer or dowload an app/widget with a time counter, why is that everybody is always waiting other people solve their problems instead fixing them themself or find a workaround?? so after playing the first time and beating the game you never play it again to avoid screw your steam final game time???

Drive it home backward.

i think when i uninstalled and reinstalled steam a long time ago, i lost all my play time, but i'm not sure..

What about a way to admit that you got addicted to Sonic? xD

Long long loong ago I used a program called Sam picker (or something like that), it allows you to just "set" your gametime of any game on steam.. (as well as reset achievements so you can earn them again)... not sure if that thing is still around though :)

you can use a split program... or a timer or something.

You could play the game in offline mode, so steam wouldnt count the hours. So if you have 4 "extra" hours, play the game 4 hours offline.

A friend of mine once contacted support to have achievements and playtime wiped after he cheated in TF2.
Surprised he didn't get a VAC ban... maybe it's because he came clean.

use Raptr too track your hours and only run it while you are playing.

I like to alt tab out of games i am playing, check the net and go back to the game. It inflates my playtime a lot. Stopped bothering me after a while.

This could actually be usefull to drop Steam cards... :p

I consider myself mature enough for this awkward world, but after your post, I couldn't help myself and immediately thought about this.

Steam is water vapour. Try condensing it.

Don't think so.

Not that I know of, but a friend of mine uses xfire to track his playtime, or raptr as someone mentioned. or you could contact support but tbh they'd prob be too lazy...

Try launching the game and put your clock back while in game
