Im hoping it was another game that got cancelled.
, I was just playing some of sleeping dogs that's a fun game. That company is mismanaged and they think every game they release will sell 10 million copies. They got Sleeping dogs on the cheap and are disappointed it only sold almost 2 million? 

I don't even remember the ending truth be told.

but that seems mad low to tell the truth I thought it sold more than that
