There is no study in existance, at least one that is peer reviewed which shows that violent video games are attributed to anti-social behaviour or
violent behaviour.
What studies to show is the act of sitting in your room for 12 hours a day, days on end, will certainly make you anti-social and possibly manic
deppressive, but it's not the video game that does that, it's the overrall lazyness associated with staying indoors for extended periods of time.
As for the time frame, most major games are released during Holiday schedules and the end of yearly Quarters.
November being in the mid 4th quarter, you see a lot of releases. Same thing with April and July and so on.
ETA: Considering the average production cycle of any major video game varies between 2 and 5 years, these were thought up and started on way before
any OWS movement.
