games that have networks that require usernames usually just have people that put in something they think is quippy, or their character's name/s in some form. s.rogers or hiro or something. not everyone wants to put the effort that we put upon ourselves to come up with a witty username for our chars into that icly in a game. half the games out there don't let you pick. i wish more were like that. just make my char be first initial.lastname. works for me. and my character.
