1. Modeling the physics of the equipment CORRECTLY is about as complicated as the aerodynamics of the plane itself (or even more). Because of this reason, modern era sims either compromise on all aspects, or concentrate on the equipment since, lets face it, this is what wins these fights. Even then, the performance of radars, missiles and sensors is greatly over estimated. The enormous modeling complexity would mean that you will have a very small available plane selection - if HTC would like to maintain its modeling superiority (at least in most aspects) over other games that is.
2. ACM does exist because real weapons systems fail very often in real life. Radars still loose contact, missiles still get confused and electronic warfare is a great big unknown (closely guarded secrets). If those are modeled right, it may happen in the game too. However, the speeds which are typically more than double those of WWII and quadruple those of WWI mean that you are fighting an enemy which appears as a single pixel on the screen most of the time, except occasionally when he streaks by. In this respect, WWII and WWI flight sims are MUCH more attractive to a computer gamer.
