I'm really impressed by this project and I hope it garners well-deserved success. the F/A-18 is a beautiful bird and a simple-to-use, but simulation-oriented title like this is great to see.
If content suggestions are allowed, something that might make an interesting add-on someday if this project expands to those regions may be a mission editor. If a few air and ground units are developed eventually, then with even with basic, editable briefings and a simple asset placement system, the game's content pool is infinite. Edit your briefing, place your allies and enemies, and off you go!
