You’ll be off to creating your first game in no time! For those of you wondering what game engine to use to begin creating your first game, we created this big list of game development and creation software to help you understand what tools you may want to research. These 37 game development tools range from minimal to heavy coding and all come with their own pros and cons. Coming up with a cool game idea, gathering assets, and beginning the development process takes a ton of time and effort. To see a list of categories for apps and games, select an option below.If you’re just getting into game development, understanding where to start can be a pretty big challenge. Note: It may take up to 24 hours for changes to reflect on your app's page on Google Play. If you think other tags will better reflect your app or game, you can use Search tags, the category filter, or scroll through the list under "Other tags" to find and add them. Select tags under "Suggested tags" to add them.In the same section, select Manage tags to start choosing and applying tags.In the "App category" section, select an application type and category.On the left menu, select Grow > Store presence > Store settings. #Video game software categories how to#Below are steps on how to choose a category and add tags to your app: If your app has more than five relevant tags, we recommend you choose those that are most strongly associated with your app. Your app or game can have a maximum of five tags. In which case you should re-evaluate your tags to ensure that the five most relevant tags are selected. We recommend that you only change your app’s tags if you make significant changes to the content or functionality of your app. This game should not have tags like "Stunt driving" (the fact that you could do stunts does not make it a stunt driving game) or tags for related game genres that might attract similar players (such as "Motorcycle racing" or "Truck racing"). It should be very clear to a user who is unfamiliar with the app and why the tag is relevant based on the store listing or initial in-app experience.įor example, a multiplayer racing game with vintage cars might have the tags "Racing," and "Car racing," because they reflect what the game involves. You should choose tags that are most obviously relevant to your app. Users can view apps by using a browser and the Google Play app. Categories and tags help users to search for and discover the most relevant apps in the Play Store. You can choose a category and add tags to your app or game in Play Console. ![]() |
