But pilots put the map on their laps, some put them on their yokes, but they don't tape them to their HUDs.
That's different. Let me explain my example with the 3DS vs. Wii U when playing Monster Hunter 3 Ultimate. On the 3DS, just like with your real world example with the pilot, the main screen (
or view) is very close to the second screen (
or lap) and so it makes sense to have the map on the second screen. On the Wii U it feels more natural however to have the map on the TV.
Compare this with games that have continuous flow of action between the two screens, e.g. Sonic Rush on DS. Now try imagining Sonic Rush on the Wii U and you'll understand my point: the TV is often far away from the second screen (
the Wii U GamePad) and due to the viewing distance, what's on the TV and what's on the second screen looks different in size. You have to adjust every time you switch between the screens. A pilot doesn't have to do that as the map on his lap is within his periphery and the "action" is right there in front of his eyes.
