You will learn many different skills, including: - Graphics: Displaying 2d/3d graphics, using the GPU, shaders, etc.. - Multiple Clients: Dealing with multiple browsers or OS's - Realtime Communication: Multiplayer will require sockets or web-rtc to provide a realtime experience - Database Tech: Depending on what DB you choose, you'll learn CAP theorem and other trade-offs. - Algorithms: Developing gameplay logic, rendering logic, AI logic. - User Experience: Making the game fun, getting feedback and implementing sugguestions. Making a game is also very satisfying, which is important to prevent burnout during the project.
