I wrestled with whether or not to add shops for quite a few weeks while creating this
game. Originally, this chapter was going to be more about units(Which was quite unneeded),
but I've changed it to be about shops. Shops are groovy, with lots of spiffy stuff in them
that you just can't wait to get your hands on. The location of each shop is defined in
the specific mission, but extra may be added at the narrator's discretion.
Shops are complicated, but most of the tricky bits are added in the mission itself.
It is up to each individual mission's creator to determine the inventory of each shop, how much
each item costs, and what you can sell your items for.
The principle behind shops is rather simple:
You give money and get goods
OR
You give goods and get money
