In all games, you can play as a guest without registering by logging in without a password. If you enter a nickname, that will be used (but with an asterisk in the beginning like any guest), but if you do not enter any name, a default one will be given to you, with the default name differing between all Atelier 801 games (see below). Guest names are easily identifiable by the asterisk (*) which precedes their name.
