This document summarizes the evolution of game development from the 1960s-1970s to present day. It outlines how in the early days, game scope was limited, costs were high, platforms were few, and the market was niche. Over time, development budgets and team sizes soared, numerous platforms emerged, and financial models changed. However, some things stayed the same - a bad game remains unpopular, simple designs are still effective, small studios can still succeed, and hardcore fans endure. The business now rivals the movie industry in financial terms.
