Those questions were not specific to orbiter. "Game AI" can be any game. And NR2003 has the best of that. Right now, "REAL AI" is not possible, but it may be in the future. Right now, the "Game AI" is the best that we've got. Which technicly isnt real AI, but it's "AI" enogh to do it's job, which is basicly to give you something to interact with.
Online is a good way to challange your skills against others, but if you can't go online or have the disire to go online, the "AI" is good enough. And yes, I would like something easier than OMP. And (seperatly) some sort of anti-cheat system to go with it.
The idea for my simulator was originally disigned for racing motor vehicles like NASCAR Sprint Cup cars or NHRA cars. But the engine is going to be so complex, that it allows for flight. And the AI is probably going to be the biggest hold up. I want them to be able to be given a black flag unlike other simulators which never flag an AI.
