First time poster here. And I could not have picked a better thread to kick things off in.
In my view, it must be remembered that a flight simulator that is sold for the PC (or any gaming system, for that matter) is still, at the end of the day, a GAME. While I am all in favor of realism and technical details, even a hard-core simmer like me has to admit that it can become incredibly overwhelming at times and it takes away the "fun" factor of the game.
The way I see it is this. You want to be realistic? Then you have to consider the fact that professional military aviators learn everything about the aircraft before they go on their first flight. In other words, your first flight is not the time to be trying to figure out where the jet-start switch is located. But that is often what you end up doing in a study-sim - a lot of trial and error involved. In my view, the simulator assuming that you are already a qualified combat aviator ready to take on your first combat mission to the point that all the "little things" have been accounted for is far more realistic than making a player learn where every switch is located and learn the exact protocol for getting the plane started on the ramp.
There are a lot of things the '80s and '90s flight sims did well, but that is at the top of the list - making you feel like you were a combat aviator right out of the box, as opposed to a noob.
Part of the appeal of LOMAC and the SF2 franchise (which I consider to be LOMAC-lite) is that they have that '80s and '90s feel to them. All the little things are taken care of, all you have to do is focus on the big picture. Within that big picture, however, are many small details that you do have to pay attention to and that provides further realism towards the simulation.
