Basically you have an above average shooter that is basically commanding you not to trade it in after your done with it if you want to complete it 100%. Its crytek's way of shooting down used game sales by implying that the only way for you to get the full experience of the game, you have to have it fresh in your mind for SIX MONTHS! Now thats not to say you have to play for six months continuously, but that you actually have to remember that you still have that one achievement to get and you can't get it for a half a year.
Now imagine for a second that you don't want to renew your gold subscription and but it runs out before the timer stops. You can't get it.
And I know what your thinking...."Well numb nuts why don't you just up the calendar six months to get the achievement and be done with it?" The answer is simple. Xbox live updates the clock for you to stop that from happening, so in order to play online to begin with you have to be up to date with their clock to stop that from happening!
So this one gets my vote, and it just so happens I took this game out of the library in order to get the achievement haha.
(In second place is the achievement you get for finishing Fable 3, because having to play that game from start to finish is an absolute chore.) --- "This Year in Jerusalem."
I got the worst. Over the Rainbow in Bully. Not happening.
Oh, get over it, baby. It's not like it's actually difficult to do. Too scared to meet the requirements? --- Why do people... betray one another? They might as well... all just die instead. Welcome to my kingdom!
