I'm recalling the time I was sitting in a cold glacier in Everquest and wondering what the fuck I was doing with my time. Had the same revelation in Dalaran in WoW, same thing doing Sky in FFXI. And today it just hit me as my shitty (and I use the term loosely...) "team", let themselves be steamrolled and spy capped 4 times in a row.
I hate this game. Why am I playing it?
Everyone eventually hits the "wall" for a game. Take time off from TF2 and move on to something else. You may eventually come back, or you might not.
