In an actual game, its practically impossible to gain all of the dragon balls - unless I guess you have a team of 7 or more people...
The reason for this is because a person can only carry 1 dragonball at a time. All a person has to do is grab one dragonball from your pile while you are getting other dragonballs. The only time someone gets all the dragonball is when the other people *let* them. They either let them so they can mess around or they let them so they can camp the dragonballs and steal their wish.
Characters should be able to carry as many dragonballs as they can get their hands on. Every respectable character in dbz has telekinenisis - Captain Ginyu carried all of them in this manner. This way, if someone goes through all the work of getting the dragonballs, without getting killed, and finds a safe place to drop them, then he can actually keep his wish.
