The number of video games that are available is growing everyday. The Covid-19 pandemic has resulted in people finding solace, support and a community through video games
Before beginning to create a game you need to look closely at what makes a good game (conduct an inquiry) and develop / write a proposal outlining a worthwhile project that is in scope and will achieve a particularly valuable goal.
The outcome that you propose will be entirely up to you and may well be the game that you have for your project.
This is an individual task, although you may work with others on a similar inquiry topic.
