I was playing Tyranny (Obsidian's new game) and I was curious to see if their lore system could be replicated in RPGmaker.
During dialogue, some of the text in the text boxes is colored orange or green, then the player has the option to right click on those words. This brings up a separate, floating, window (without exiting the conversation) which has its own text. These boxes then give the lore related context about whatever other characters are talking about, so that the player is never out of the loop.
For example, if there is a line that says "bobby is coming over tomorrow" and Bobby is in green text, the player can right click bobby and the separate text box will say "Bobby is Joe's best friend who did this and this and this when they were in school together."
