A certain level in The Simpsons Game is really hard for me to beat myself so I figured that I can finish it with a help of a mate so I'm bringing the game to my friend's house. So I'm bringing the game and my HDD to play my save file. My questions are: 1) I will use my 360 hard drive on their 360. Will I be able to use my account on there? 2) Will my achievements still be intact? Also, if I ever get new achievements, will I still have it when I play the HDD on my own 360? 3) Do I need to go on Live to save the achievements or will they be stored on the HDD? Their 360 doesn't have a Live connection because they don't have Internet. Thanks for the help in advance.
