Phantasy Star Universe

To have a message box include an image of your character's face on screen, put "@n" before your message. N represents any number between 0 and 9. So you could put "@0 Hey there!" which would display your character with a 'laughing' face and the message "Hey there!". Alternatively, you can just hold down the right trigger when you press OK with the on screen keyboard, and you can select the facial expression you want to use from an on screen menu.

You can change the colour of the text in a message box by putting {COL} before the message, with COL representing the first three letters of the colour you want your text to display as. So {RED} would give you red text and {YEL} will give you yellow text.

Lastly, you can play sound effects by putting %n in a message box, with N (again) representing numbers. It starts at 1, but I can't remember how high exactly it goes. It only works during missions, not in lobbies though, and covers all the sound effects in the game. My personal favourite for annoying people is %15 :)
