Steam – How to disable play time tracking

You also have to take into account the fact that since the "Total playtime" feature has been introduce about two years ago, it didn't count all the hours you've been playing before. According to this article, gameplay hours are recording since March 2009 exactly. For instance, I've been playing CS 1.6 A LOT several years ago, and I only have something like 30 hours "on record" (because I don't play it anymore).

Steam now reports all-time play time Finally! The stats seem to have started their count about a year ago, so it's not all-all-time, but it's a welcome addition nonetheless. Other programs like Xfire (and even WeGame!) have recorded and reported this info for quite some time.

I know, it can be kinda depressing for a hardcore gamer ;)

Personally I found running many games at once does not work for me, I have gotten cards when it was 3 or less games at once.

Cards generally drop once every 30 minutes for most people when playing a single game I am unsure if this average stays the same when using multiple games.

I do not believe there is a limit to how many you can obtain in a day since there is a limit already associated to the total amount you can have.

Things to keep in mind

Level 10 you start getting foil cards.

Every 10 levels you increase your chances for booster pack by 20% at 100% it has (doubled)
