Yeah. The out box would be the "game" talking to the player. Like "missed". "Welcome". "Select your weapon". And stuff like that. Or in my version, when you want to attack for example it prompts you to choose your weapon. That information should be displayed in a OUT box.
Of course this solution is to make it more simple, so that its window displays certain things. The inventory box maybe the only one that has multiple functions, like displaying the itesm or the stats or the powers depending on the command given. I ll probably have the first code ready in less than a day so we can work from there.
