Well, "easy" isn't my comfort level yet.
First, I just want to practice flying the plane without getting shot at.
Then I'd like to go one-on-one with a bogey.
Ideally, there would be the option to set up a situation and have the bogey fly a specific path, so you could practice different ways of attacking or countering it. (Just like a chess problem.)
And being able to see a visual representation of your flight path would be invaluable.
