When creating a private game, the players text box should contain your username

[salty-horse]

When creating a private game, you have to specify at least two users on two lines.

I wanted to start a game with a friend, and didn't understand why it didn't validate when I just entered their username.

I realized that I had to enter myself as well. It would be much more intuitive it it prefilled my name (still allowing me to remove it if I wish to create a game where only others would play.)

You could be really annoying with this, theoretically
