What an awesome game!
It truly captures the dynamics of cross country racing, with an elegantly simple graphical interface.
So good is the game, that I feel similar mind processes going on while playing the game and while racing in the real sky. The basics, at least.
I'd go so far as to say that if you can reach the 100km goal in less than 100min, you have a working understanding of XC racing.
My best time is 89min. If you beat that, I'd love to hear how you did it!
Making equivalent 'real sky' decisions, with the sensory overload and fear that comes with real flying, is another story.
