Game developers could do it fairly straight forwardly but the demand for multidisplay functionality isnt really there. Supcom had a 2nd monitor option to render a 3d map but i cant think of any other games that do a separate function like that. Ac6 has a minimap? Fat chance getting something that cool and involved with a game you cant completely mod or make yourself though. Itd be really sick to see something like it on ac6 especially. I miss 4/4fa’s HUD.
If only i knew other people who appreciated that!
