In fact, a good game name is just like your name in real life. Once you choose the name, others will look at you differently. If you want to be more popular, you can choose a name like "This is better than that." "Bi" is a rubbish name. This kind of name is fashionable, but it can easily make people look down on you and think you are a frivolous little brat.
If you really want to have a good time in the game, it is best to choose an easy-going name that is more pleasant to people's ears, such as "Mushroom Elephant". The specific name is up to you. Making up your mind is nothing more than a matter of style.
