I have a notebook with some scribblings for a Fulcrum base virtual squadron. Concept was not unit or nation specific, allowing for a vast variety of scenarios across all maps. Milsim adjacent, no ranks but a focus on procedures. I even thought of assigning airframes and tracking hours for wear and tear, and liveries for the jets reflecting that - The more time on aircraft, the more weathered the jet.
I wasn't sure if there would be interest for the FC3 jet, so I shelved the idea. Now with the FF coming along I may revisit it.
