Are you addicted to Farmville?
The game requires no special skills and is very simplistic in concept. Therefore, its very easy to get sucked in and ultimately hooked.
It has evolved over the years to add VOLUME and as such can be very time consuming if goals are not set.
It seems that a majority of the players that I have encountered get sucked into every "new" Quest which can undermine one's goals. I totally avoid these with the exception of being "neighborly" by helping out my much needed neighbors.
