If anyone here is even semi-serious about combat flight sims then you have to have played at least some iteration of Falcon4 at one point. If there is a better campaign engine out there I haven't seen it, and I have seen them all. The most digusting thing about this is that campaign engine is over, way over, a decade old. A completely dynamic campaign were everything happens in real time regardless if you are flying or not? Absolutely brilliant, nothing surpasses it to this day, kind of sad considering how good A-10C is that the campaign system is something out of Ace Combat. Maybe someday some developer will stop being lazy and give us an updated version of the Falcon4 campaign engine, hopefully it is ED.
