A game u may be lost in playing (story wise) and finally understand wat was goin on after u finish it!
You would not really care because the breath taking scenic view of the graphics is so compelling that it wouldn't matter to you at the moment (when u started the game and played for a few hours).
But soon u would start to question yourself that what is really going on and ..slowly but surely you would start to lose interest.
Things which seemed quite intriguing would start to become quite annoying ...e.g. wen u would have repeat a certain quest in order to proceed further ..da sound of entering that alternate reality would become really annoying as u would do it so many times! esp. if there is some sort of mic announcement ...
another example is that in the whole game u wont be running much (mostly walking) as you would be saving your energy most of the time!
When u come 2 a point of giving up....this is the time to press forward to finish da game ...as near the end, it would be really rewarding to see how all the little pieces of story come together and why u were doing all this!!!
