MMO would be interesting, but difficult to implement, of course I've been thinking about it .
I do, however, lead a project attempting to simulate the various Macross craft, and, obviously, move into multi-player. But development is slow of course, hehe.
I've got several developers helping out, but very few of us get any serious hours to devote to the project (read >2 hours a week, tops, lol). BUT, I have got a good VF-1 model started (fighter mode, no others yet, sorry, I'm trying! lol). I'm basing the models on real world physics/aerodynamics, etc., since it's my area of expertise. So it'll be as real as I can fake it .
We should have a windows binary coming out soon, I'm hoping in the new few weeks. I'm trying to get a simple HUD done soon and also trying to fix the VF-1 aerodynamics, they got messed up some when I did a major overhaul of the F-14 aerodynamics. And yes, the VF-1 is aerodynamically similar to the VF-1, I've had this argument before, hehe. Size is more or less irrelevant to the way the aerodynamics are built up. And yes, I realize that FlightGear and X-plane are out there, before I get hit with those questions, but they don't do everything I need, and aerodynamics aren't that hard.
So shoot me e-mails and keep bugging me to get stuff done, lol. Right now it builds under windows (latest CVS version, no package has been made yet) and has a really crappy HUD, i.e. 3 lines that rotate but don't pitch as the aircraft does. I'm having to learn OpenGL to do this as I go, WHEEEE! And yes, my close friends think I'm nuts for doing all this.
And sorry, no weapons yet either. After I get this next release out, I'll try and find out if people want network play/weapons first, or gerwalk mode. Don't even talk to me about Battroid yet, that's gonna require some serious work to fake.
BTW, the screenshots on the website aren't in the game, Dan did them for us several years ago and we just now have a graphics engine that we can pull models into (Open Scene Graph). So sorry for the teasers.

Oh yeah, and it's FREE (*cough and worth it*).
