If you haven't already, be sure to checkout MicroProse's [1] "modern" retro flightsim, Tiny Combat Arena.

Sure, it's beta and continuously in development (and likely won't be finished, ever), but still, you can take off in a Harrier and blow up stuff. The graphics are charmingly retro.

VTOL VR is a pretty great VR first mil flight sim. It has f-18, f-35, and apache like vehicles. They recently introduced wind effects and EW. Allegedly the radar cross-sectioning is better than DCIS (actually accounts for orientation towards the radar)

Tornado was another terrific sim. It had the best mission planner and immersion even though its simulation of the ALARM was busted. Digital Integrations? Don't remember if that was the publisher.
