I was in the same boat. Nowadays I barely play any games coz of MPGH. But in terms of affecting my everyday life it hasn't changed me much tbh.
The only reason I dont play as many games is because most of them bore me. MW2 is too easy, BO sucks, and most other games I have beaten at least 100 times. Im waiting on Portal 2 to be released, and when I do Ill be playing that all day long.
