Introduction to Game Systems Design. A Step-by-Step Guide to Creating Balanced Games

Good game systems design is key to the success of any game. System designers lay down the basic rules of the game and its balance, set the values for character and weapon attributes, define how artificial intelligence will work and how player interaction with the game will occur.
This book will teach you how to create game systems from scratch, work with the main tools for system design, evaluate and adjust game balance, test systems, and work with player psychology to create the gaming experience you need.
