A game very similar to this was released a few months ago. Using Google Maps Street View, you were dropped into a random location and had to navigate your way to the nearest airport. It was sickeningly frustrating!
The student version is only £15 per month. Which is great, as students don’t tend to be able to shell out a lot of money up-front. The only issue I find is that the student version is pretty low in features. If it had ‘a bit more’ I would join instantly.
