Modern game development involves leveraging third party products to reduce the workload on the developers. Components such as music, images, characters, fonts and trademarks among others are used as third party components. Many games may also require the storage of user data.
The external components may come with patents, copyright, license, and intellectual property issues. Games that have to adhere to data privacy laws [1] with their user data which can vary based on country and region.
To deal with the issues related to legal matters, a legal expert should be consulted before releasing the game.
An instance of this pattern can be seen in the post 72695. The developer asks about the implications of allowing users to have names of real-world personalities in the game.
