You have a small collection of retro video games and you want to upgrade the previously built microservice API to manage them. In this lab, you will build upon what you worked on for Part 1, by adding RESTful update and delete functionality for a game entity. Lastly, you will create a bonus endpoint, that will allow the user to filter the results by game console.

This lab builds off of a previous one. If you have not already completed part one of this lab series, please do that first before continuing with this lab.
