I was planning to rent this and wanted to know how long is the single player for it? also from what it sounds like that the game is not being played online by alot of people?

DUde no one is playing this, neither in the single player, it doesn´t have a single player mode, it´s just a practice mode, those are the missions, the missions are only practice
