Ren'Py vs Stride

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.

Stride is a free, open-source C# engine for building 2D and 3D games and interactive content on desktop and VR. Game Studio manages assets, scenes, sprites, interfaces and curves. The engine provides physics, navigation meshes, visual scripting, physically based materials, light probes, particles, post effects and customizable shaders, with DirectX 12 and Vulkan graphics APIs. C# 14, .NET 10, asynchronous scripting and hot reload are supported. Native Oculus and HTC Vive support includes VR previewing from the scene editor. Stride exports to Windows, Linux, Android and iOS, and is free to use, modify and distribute under the MIT license. Listed development requirements include Windows 10 or 11, an x64 CPU, a Direct3D 10-or-newer GPU, 4 GB RAM and 5 GB disk space. The project describes itself as community-driven, without full-time developers dedicated solely to its advancement.
