Hi to all, I just have this question please, & if it's been asked, I have missed it in my searching, so sorry, just tell me where please:

When do you consider the game you are playing as being "completed" Is it when you have gone through the single player content by your own efforts, or even by the use of save file work-around, and that's it, done dusted game completed in, 'X' hours - move on to the On-line etc ?

It's that I keep hearing on reviews, this game is Short, not much for the single player to work on, you will finish in about 10 hour's, etc etc. but at what level of play? Sure, skill level recruit or rookie, etc it may be so, but what about the rank ups through to; as in COD Modern Warfare (Veteran) ranking - ??

Do - players skip the difficulty levels in the single mode not wanting to go through the game again at harder and then harder still level? If so, why are the rank ups in the game at all? Thanks for your time etc.
