There is another way... Go to his house with out asking and just like ring the door bell and don't tell him that your coming over to his house then u tell him u want something to drink he goes to the kitchen and gets it run up to his room and press......DELETE THE GAME!!! Then run back down before he goes back up and spill the drink he was getting for u then stall time while it is uninstalling.
then u act all inoccent and while u walk up with him to his room plan something for u guys to do on like saturday or sunday and then u say "Can i try out that game u always play" and then let him relize that it was deleted then he gets all anoyed then " then u pretend u didn't noe wut happened and when u go out with him on saturday or sunday buy a new game that u and ur BF to play ...... and TAH DAH ur done!!!
