Unique (i.e. not fly-by-wire) flight model. Much faster than A-10. Lots of air-to-ground CAS goodness. STOVL is awesome. Rearm and refuel at road-based FARPs. Cool weapons: APKWS laser-guided rockets, GPS an/or laser-guided GBU-54s, AGM-122 Sidearm anti-radar version of Sidewinder.
Definitely try it out. It is challenging and rewarding to fly well.
