I suck at a lot of games.
For most games, I don't care about sucking. I want to get barely good enough to finish the singleplayer mode once on medium/standard difficulty (or easymodo if that's really what it takes), and that's it. There are only a handful of games I ever cared enough about not to suck.
Of course I like to believe that my many years of playing games of all kinds of genres have infused me with a sort of inherent non-suckage, but while I
can 'pick up and play' just about any game ever made, the multiplayer community for most games still seems to be intent on proving just how much I suck the moment I get online.
Seiously, they're all like "Oh hey it's that guy, let's humiliate him so he thinks he sucks at every game ever!" It's the only reasonable explanation for me not being awesome at games.
