NDA's are the means companies use to keep all info
( good or bad ) of an upcoming game under wraps.

This ensures the maximum number of subscribers will
at least try the first month which, at the very least,
will guarantee income from purchasing the game and
the first months subscription fee.

The top goal is to make money off of the endeavor. An
acceptable one, however, is to break even the costs
required to create it.

The net is basically an amplifier for the entertainment
industry. If the product is amazing or terrible, word of
mouth across the net will raise the repercussions of it
exponentially.

Since everyone can find fault with anything, they try to
keep the info released to an absolute minimum.
