Having completed the achievement to finish the story in under 30 hours, my next playthrough will also be based on realism. I like the idea of turning off the radar, as I want to use the printed paper map more. Yes, there is a map in the main menu, but I have always liked printed maps.
Is there any option to change the actual game time? At the moment, one minute game time is two seconds real time. If that can be slowed down, that would be really neat!
