CRYENGINE vs Ren'Py

CRYENGINE is a game engine for building projects targeting PC, consoles, mobile, web and VR. Its offering includes full source code, engine features and access to supported platforms. Developers can use C++, Lua or Schematyc visual scripting, along with multiplayer tools and mobile export. The Sandbox Editor creates worlds without baking and exports them as they appear in the editor. Rendering includes dynamic global illumination and a physically based rendering workflow; physics simulations account for physical properties. The engine also includes particle tools, animation systems and a physics solution for dynamic destruction. CRYENGINE can be used for free under royalty-based licensing: a 5% royalty applies when a project ships, while the first $5K in annual revenue per project is royalty-free. Documentation includes guides and tutorials, and community channels include Discord and GitHub. The maker was founded in 1999 and is headquartered in Frankfurt, Germany.

Ren'Py is a free visual novel engine for making interactive stories and life simulation games with words, images, and sounds. Its script language handles visual-novel writing, while Python can be used for more complex game logic. Default games include menus, automatic saves, rollback, predictive image loading, and mouse, keyboard, or gamepad controls. Creators can customize screens and styles using the screen language and Python. The launcher builds Windows, Mac, and Linux games from any of those desktop systems. Ren'Py also supports Android export and can package games for WebAssembly browsers, though web support is beta and lacks networking and multithreading. It targets Windows 10 or later, macOS 10.10 or later, Linux x86_64 or Arm, Android 5.0 or later, and iOS 11 or later. Building for iOS requires a Mac and Xcode, and that support remains a work in progress. The engine is free for commercial and non-commercial use; most is MIT-licensed, with some LGPL components whose terms distributors must meet.
