Whether it is or it isn't, it doesn't bother me in the slightest.
We all heard the report that Metal Gear Solid V: Ground Zeroes might be only about two hours long . Recent reports have indicated that in fact, it's longer, while the developers seem to have acknowledged the two-hour estimate by defending it.
I know everyone's all up in arms about this, and I understand why. After all, you paid a certain amount of money and if you feel you were short-changed, that sucks. So, if you pay $40 for the physical retail copy of Ground Zeroes on PlayStation 4 or Xbox One, and it only lasts two hours, you might be annoyed. However, I'm not sure I would be…I mean, provided I felt satisfied. "Satisfied" is a very subjective term, but I think everyone knows where their satisfaction level lies for each game.
The bottom line is that quality is not contingent on length. Sure, you might want more of a great experience, but that's not what I mean. If the game is great, if it didn't have a lot of filler to make it seem longer, if it didn't feel rushed, you're going to enjoy yourself. You'll finish it with a smile on your face. This is ultimately what matters, and I believe I can smile at the end of a 2-hour adventure and a 200-hour adventure.
