And what would you chaps say/think if you discovered the sim's planes were flying differently to the real ones, in that they were modelled 20% lighter? Such that the full tanks were making them 10% closer to reality but still performing 10% better than real?
I'm not saying that's the case, but how do we know it's not? Have any of us flown a real one, right to the edge of it's performance envelope?
My point is that our simulated planes are an abstraction already, and the fuel-load is just an abstracted component of that abstraction. The only reason it matters to you is it was once variable and now it's not. Would you care if it had never been variable? No, you wouldn't, you would simply have got used to their performance envelopes and flown them accordingly.
I think the best way to make my point is with this para-phrase...instead of trying to adapt the world to you, adapt yourselves to the world. These are the planes you have, right now; try to survive in them, try to kill in them, try to do your vDuty in them, as they are. Because they are, at any given time, what they are. Hated, loved, as were the real ones, for this or that.
I hate the N17. It's fragile, under-gunned, has a lousy sight. But it's what I'm issued with right now, and I do my vDuty in it to the best of my ability. Just like the real chaps did. My lord, if they could hear us!
