Has your life improved since you quit?
Pretty much the same. Just shifted my focus to OW/CS
Do you get bored enough to feel the urge to come back to TF2 often, or are you satisfied enough with where you are (or dissatisfied enough with TF2 when you left) to not even consider it?
I surf mostly. I do miss the movement but other than that, pretty much no urge to comeback unless money and competition is flourishing.
Did you have some other, non-videogame hobby to spend your time on, or did you exit into the world with no clear plans for what to do next?
Still make beats, workout, and compete.
What was the main reason that you decided to quit TF2?
Didn't get to participate in an iSeries.
And, of course, why do you browse a forum for a game you no longer play?
See if tournaments pop up around my area.
