This is actually just a rerelease of Falcon 4.0 with extensive updates. A small dedicated group has been adding to, and fixing every little thing from this sim. Now I guess it is being released for sale with some further enhancements.
Graphics aside, this is by far the most realistic recreation of modern combat experience. There are hundreds of pages of information, and yes some key presses are like alt-shift-9 and such. It's very daunting, but for the small worldwide community, it's still the sim to beat in terms of scope, detail, ai, and dynamic campaign.
There used to be a quite large market for these types of games 10 years ago...unfortunately those years are gone. I have long enjoyed Falcon 4, and hope it resells enough to raise some eyebrows of producers to invest more money into the sim market. perhaps wishful thinking.
