My favourite store which had the whole upper floor to itself (only right, considering it sells teleportation):

Aww screenshot doesn't show properly: The Sword in the Stone, selling Translocationaries, Clothing, and Playthings.

Realistic, owned a arcade mall strip and only earnt $100

Not sure if I missed anything but I picked the empty shops, then placed the stores in them.

It looks like a lot of work in the graphics and it really does have that adelaide arcade vibe, so nice job on the art. It was fun reading the description of each shop as you added it.
