Today "Microprose" is just a name owned by a publisher, not a simulation dev studio like back in the day (that I'm aware of). The owner wants to make money on that name and who can blame them.
BTW, Microprose also published games in the 90's that they didn't develop themselves, including one of my all-time favorites: Subwar 2050 (developed by Particle Systems).
EDIT: Would this not also include Falcon 4.0, or was that just the use of the more popular "Microprose" name after a Spectrum HoloByte buyout?
