Not sure about console game prices, but on PC they drop significantly with time. If buying online on PS4 is similar to Steam and Origin, you won't have a problem getting them cheap.

I think the moon idea is best. You can check out the craters, and if you make sure not to move the telescope, you'll be able to notice the movement of earth and moon relative to each other (i.e. the moon will edge closer to the edge of the scope's field of view as time goes on).

Then they will charge for their services. We will end up paying for google the same way we pay for TV channels (for those of us who still do...)
