The last thing that digital art and design will allow you to do is design games. Although you may need to learn other skills, such as coding and programming in order to make the game playable, but you will be able to have all the skills need to design things inside of the game, such as characters, objects and levels, and other screens within the game.
Being able to make digital art can lead to you finding more fun things to do in games, such as being able to build or create things in games that have level editors, and games that are made for you to build things.
