Introduction to Game Systems Design

Description

The Complete Beginners Guide to Game Systems Design for Every Aspiring Game Professional

Game systems designers are responsible for creating and balancing the rules of a game. In addition, they create the data that drives character attributes, weapons systems, and all other aspects of a game. They make everything fit together, so games are playable, exciting, rewarding, and fun. As games get more complex, this work becomes even more important; and Introduction to Game Systems Design is your complete guide to getting started with making great games.

Dax Gazaways step-by-step, hands-on approach draws on his decades of experience building AAA-level games (including games in the Star Wars and Marvel franchises). Writing for aspiring game professionals, even those with zero experience, he introduces all the principles, techniques, tools, and tips youll need to succeed.

As Course Director for a world-renowned university game design program, hes successfully taught thousands of newcomers to the field. His proven examples and analogies help you rapidly understand key concepts--so you can start designing tomorrows legendary games.

• Explore how game design roles and subdisciplines fit into the game development process
• Ask the right questions to create better designs
• Understand the purpose of modern game design tools, from flowcharting to game engines
• Use spreadsheets to make complex game data far easier to manage
• Imagine new game ideas and build them out with systems and data
• Use attributes to distil and quantify aspects of  life into games
• Test and tune a games balance, find problems, and solve them
• Balance complex games with large collections of objects
• Create campaign mechanics that use exponential growth
• Make games easier, harder, or more accurately balanced for a target audience
• Leverage communication, psychology, and rewards
• Understand probability from the basics up to practical use in games
