I haven't been able to game properly lately. Everytime I try to play a game, I just stare into the pixels or polygons on the screen, not paying any attention to anything, not even to what objectives I have to accomplish to move onwards. It also seems that I've lost that sense of joy when playing games. I cannot recall the last time when I truly enjoyed myself playing a game...
It's as if gaming has stopped becoming a pleasure, and more of a chore to me.

I am saddened by this realization.

Maybe if you did something to loosen up a bit you'd feel better. What I like to do is play F-Zero X and kill all the other racers XD Or you could play Goldeneye, stand still, let enemies come at you and shoot them all. Relieves stress pretty good.
