There still is Falcon. For BMS free upgrade, you'd need to have an old Falcon 4 original disc for installation, can be found sometimes at ebay, or such 2nd hand places. Else, if failing on the CD, there is Falcon Allied Force, in itself a solid and great simulation still, just not with the tremendous visual upgrades of the BMS package.
The major argument for BMS is the now fully detailed clickable virtual cockpit. In fact, there is no 2D cockpit anymore.
Falcon, the old classic. This thing seems to never stop flying. And that is good! And still the best campaign simulation on the market - after 16 years now, I think.
Built for eternity?
