There are three types of guests in this game. school children, business men, and old ladies. Which guest you recieve depends on where you choose to advertize. Each guest has a unique was of eating, which can be extra advantageous for certain types of plates.
I wanted all three guest types to have some type of advantage as well as a disadvantage. This gave the player more opportunities for strategizing. Balancing each guest to not become overpowered compared to the others also required quite a lot of tweaking.
Advertizing at the school is the cheapest. Children are however quite slow eaters. Business men eat quite fast since they are so busy. However, they often don't finish their plates and instead pick just one piece off of each plate. Advertizing to grandmas is the most expensive, but they are also unexpectedly powerful. With their handy walking stick they can push away lots of sushi at once. However, due to their bad eyesight, they often miss entire plates, passing by right in front of them.
