Introduction

Whether you’re an indie developer or professional studio, choosing the right game engine is one of the most important decisions when starting a new game project. A good engine can accelerate development and provide tools to focus on game design rather than technical implementation. This blog evaluates 15 of the most popular game engines based on features, licensing, support, and other factors to help you find the ideal option for your next game.

Methods of Evaluation

To evaluate and rank the top game engines, we considered several key factors: features and capabilities of the engine, licensing and business model costs, level of community and third-party support, popularity based on number of games made and number of backlinks to the engine’s website, traffic and search volume for the engine’s name and alternatives. We also took into account trends in game development like growth of indie developers and mobile/web game popularity to identify engines well suited for current market trends.

1. SceneKit

SceneKit is a 3D game engine developed by Apple for building 3D games and graphics-intensive apps for iOS and macOS devices. SceneKit provides a high-level scene-based API that makes it easy to define scene geometry, apply materials and lights, position cameras, and play animations.
