In these games, the box with the text occupies all or most of the screen. The box may have a border, like in Fate/stay night, or no border, like in Kira☆Kira. Many games use a full-screen textbox to display backlog text, and a part-screen textbox to display the current text. That does NOT count for this tag. If a game uses both full-screen and part-screen textboxes, apply both tags to it.
