Arguably, the inventory system in any good RPG game is one of the most important components.

The reason I say this is because the way in which you'd design and implement your shopping and inventory system will alter how your game is played and how quickly the player will progress through your creation.
Another factor that we will cover in this chapter is monetization. Every title needs to have a monetization story so that the player will eventually be able to make money through his or her hard work. There always has to be some kickback in the end to help you pay the bills or keep tabs on your sanity. It doesn't have to be money; it could just be recognition or an aid to your portfolio.
