Okay, this probably isn't what MGS fans wanted to hear.
We know that Metal Gear Solid V: Ground Zeroes is just an appetizer to the main course, which is The Phantom Pain . However, this appetizer – though it may be tasty – is going to be a lot smaller than we might've anticipated.
According to Game Informer (as cited by Kotaku ), Ground Zeroes can be beaten in only two hours :
"Judged just by the core story mission, Ground Zeroes is short. We completed it in just less than two hours."
However, they do clarify that the demo actually lasted four hours; enough time to play through the main mission and check out the extra modes. Besides, some players will play more slowly than others. In my experience, the lengths divulged by game reviewers are always much shorter than what, for most, is realistic. I still remember critics saying Heavenly Sword took only five hours to beat when in fact, it took me double that.
Also, don't forget that Ground Zeroes won't cost the full $60. The PS4 and Xbox One versions will cost $40 at retail and $30 for a digital download, while the PS3 and Xbox 360 installments will cost $30 for the physical copy and $20 for digital. …not sure that's worth only a few hours, though.
