In the modern gaming industry, most triple-A developers aim to impress players with video games that provide enough content to last for hundreds of hours. While this goal has served as the basis for countless bestsellers, it's also proven costly for many studios. The ever-increasing size and standards for current-gen titles have led to rapidly growing budgets and development teams with each new release. For popular franchises like The Legend of Zelda and Grand Theft Auto, this isn't a problem thanks to their practically guaranteed success. However, plenty of new and long-running series still find themselves struggling to retain their popularity and profitability under the intense demands of the gaming market. But rather than continuing to put out bigger and riskier titles against declining sales, some developers are starting to scale back on the scope of their new releases.
