I'm a big, big fan of realism...but I think the real response to this is covered by HT and a few others;
Unless you are a player who enjoys single missions which will, quite literally, last hours...you really don't want that kind of realism. Most of us are not properly trained combat pilots, so we have to learn as we go. How much fun would a new customer have (remember, HTC has to have a reliable, recurring revenue stream or our nice little pretend world goes poof!) if he/she had to spend way too much time getting to a fight (gotta move those bases WAY far apart to be 'realistic'), then micro-managing the engine(s) throughout the fight, etc...maybe I'm wrong, but that begins to sound amazingly dull and frustrating, even for someone who wants a simlulator vs. an arcade game.
We have to keep in mind that 'perfect' realism would simply NOT be as attractive as some might think. It's even possible that if all these detailed changes were implemented, that even the advocates might not get what they thought they wanted.
Gameplay, and the gaming experience, is far more important in the context of a business. This is NOT a scientific or academic environment where absolute realism is mandatory. HTC needs to construct a world that a) is worth experiencing, b) satisfies repeat, paying customers, c) effectively attracts new paying customers, d) can run well on a crazy spectrum of equipment and budgets, e) is maintainable and f) remains scalable. Oh, yeah...and it has to be FUN.
I'm always glad to see new additions and enhancements to the environment, but I don't have any trouble understanding that compromise has been, and must always be, a significant part of designing a game play system.
Look at it this way...If I have only 2 hours to play...I want the bullets/shells/bombs flying in pretty short order. That's what I'm really paying for. If it took me 15 minutes to checklist and start up, no radar to find a fight, no icons to keep from wasting time chasing the wrong contact, no fuel consumption data so I keep dropping out of the sky, etc...I don't think I'd stick around. Oh, yeah...and a base change would take days/weeks, right?
I'm not saying anyone is 'wrong'...I just personally think that we sometimes start splitting some really impractical hairs on this subject... Not that there aren't some good suggestions put forth, just that some others of them bear reconsidering.
Only, with respect, my opinion.
