You would think that with all of the warmongering we would see a bigger set of Combat Fighter Simulators for Microsoft has had a huge lock on that arena for some time. Many of the existing have adapted war planes and military installations around the world for the real world experience and that is where the gaming has lost touch as to what is really needed and definetly wanted in real world combat simulation. Up until a couple of years ago there was no real fix for that until Lock On http://lockon.co.uk/ emerged and began developing for this. As we have seen with Microsoft Simulator and many of the other popular sims; Perfection was not created over night but many of those programs delivered realism to the computer screen as it is with Lock On coming into maturity delivering a combat simulation where you are in combat and delivering as well and add-on selection that enhances the player diversification.
