I have cured myself from this sickness long ago when I realized that it is extremely hard to find good pack of peoples to playing online and when I figure out that developers designed online for grind of hell to keep their title as long as possible from second hand market. So, I said to myself: f* it, it is waste of life time. Really. And I'm completonist kind to! I like when I see platinum trophy on my list along with 100%, but shiny colourful shit icons is not worth life wasted to get something so worthless. Something breaks inside me after BioShock 2 online. I also extremely angry to unable to get pearl grade weapons in Borderlands 2 (1% drop rate in online, and FAR less in single/co-op) but well, You know...
Now I'm a toxic member of holy crusade against online playing (especially in pay services like PlayStation Minus and Xbox Dead because I already paid for f* console and f* game so there is no reason to paying more for f* sake!). ;p
