It doesnt matter if he is talking about a glass panel or the generic instruments, it's the same result. I dont see a problem with it except for the required coding. It wont provide anyone with a huge advantage in game. And what's it to you if it is "less realistic" for him?
So there is no advantage to having the regular "six pack" replaced by a glass cockpit?
Even if one flies different planes?
Even if planes from different countries have gauges in different spots, in different languages, with different readings?
Having a glass cockpit where all the flight data is in the same place, in the same language, in every plane is not an advantage?
Even if it is a small advantage, that is not really important to me.
Neither is someone else's sense of "realism", to be honest.
What WOULD chap my bellybutton however, would be any part of my subscription being wasted on something completely unnecessary to improve the game, especially if it did not exist on the a/c that are modeled in the game.
