    Stride

    Stride

    Stride (formerly Xenko), a free and open-source cross-platform C# game

    Stride (formerly known as Xenko) is a full-featured, open-source game engine written in C# and targeting the .NET ecosystem, designed for both 2D and 3D games — and even VR experiences. Stride offers a comprehensive toolchain: an editor for scene building, asset management, a rendering pipeline with physically-based rendering (PBR), and support for advanced graphics features such as real-time reflections, post-processing effects, and complex materials (skin, hair, cloth, etc.). Because it’s built on modern C# and .NET, developers can take advantage of modern language features (C# 14, .NET 10), tooling (Visual Studio, VS Code, Rider), and long-term maintainability. The engine supports cross-platform development: you can build for desktop, mobile, or VR, and target multiple operating systems. Stride is modular and customizable: you can tailor rendering, physics, scripting, and other subsystems to suit your game’s needs.

    Urho3D

    Urho3D

    Urho3D Game engine

    Urho3D is a game engine made by developers, for developers. The code is clean and well-commented. Urho3D is free and will always be free. There is no hidden royalties. It is IDE-agnostic and has no vendor lock-in. Urho3D runs on Windows, Linux, macOS/iOS/tvOS, Android, and even on Raspberry Pi. It also runs on your browsers. You need an installed Urho3D library for the desired target platform to proceed. Although the Urho3D build system also supports linking the Urho3D library directly from its build tree, this quick start section will not be discussing it here. Assuming you have been following along from the previous section, execute the following commands to create a new UrhoApp project, and then build it. The build artifacts from DBE can be found in the usual location as the conventional (non-dockerized) build environment. In fact the build artifacts from DBE should function and work as if they are built using the conventional way too.

    ggez

    ggez

    Rust library to create a Good Game Easily

    ggez is a Rust library to create a Good Game Easily. More specifically, ggez is a lightweight cross-platform game framework for making 2D games with minimum friction. It aims to implement an API based on (a Rustified version of) the LÖVE game framework. This means it contains basic and portable 2D drawing, sound, resource loading, and event handling, but finer details and performance characteristics may be different than LÖVE. ggez is not meant to be everything to everyone, but rather a good base upon which to build. Thus it takes a fairly batteries-included approach without needing a million additions and plugins for everything imaginable, but also does not dictate higher-level functionality such as physics engine or entity component system. Instead, the goal is to allow you to use whichever libraries you want to provide these functions or build your own libraries atop ggez.

    nunuStudio

    nunuStudio

    Web powered cross-platform 3D, WebXR game engine

    nunuStudio is an open-source editor + game development environment — a “studio” rather than just a library — designed to let developers create interactive 2D and 3D content through a user-friendly interface. It provides visual tools for scene editing, asset management, materials, and possibly scripting, aiming to reduce the friction of hand-coding every aspect from scratch. As an accessible entrypoint to game or interactive content creation, nunuStudio is well-suited for artists, designers, or developers who prefer a WYSIWYG (what you see is what you get) workflow instead of fully coding everything. Because it is open source, users can inspect, modify, or extend the system as needed — adding custom behaviors, plugins, or export options. It’s ideal for rapid prototyping, small games or interactive demos, or educational purposes: you can build scenes, tweak visuals, test interactivity without deep diving into all low-level rendering details.

    IsoRealms Spindizzy and Isorealms Engine

    IsoRealms Spindizzy and Isorealms Engine

    An isometric arcade-style game of skill, puzzles and exploration

    You are cartographer for undiscovered worlds; your task is to explore and map all areas of the recently discovered strange dimension of Hangworld. In order to complete your task, you take control of GERALD. However, fuel is expensive and funding can only be supplied as long as progress is being made, so it is vital to explore new areas and recover jewels. Spindizzy is a remake of the 1986 classic computer game of the same name, originally developed by Paul Shirley. The remake features true 3D OpenGL graphics and runs on a custom-built engine called Isorealms. The Isorealms engine features a complete content creation toolkit for modifying and extending Spindizzy, as well as offering the opportunity to create entirely new projects from scratch. Isorealms content creation tools are aimed at users of all experiences, from those who simply want to build new worlds to those who want to take advantage of advanced features such as Lua scripting and custom asset importation.

    KonsolScript and Game Engine

    Free and Open Game Programming Language for Windows and GNU/Linux

    KonsolScript is a free and open source, scripting language primarily intended for 2D games development. KonsolScript Development Team believes that the unavailability of games on GNU/Linux desktops is one of the major concerns why people keep using unauthorized copies of proprietary OS over GNU/Linux and that is something the Development Team is ought to address – we are doing our part to help promote GNU/Linux as a viable gaming platform for desktops both for Game Publishers and Gamers. The whole Game Development Kit is suitable for teaching 2D game programming. The end goal of this project is to have a common gaming platform for Windows, GNU/Linux, Mac OS, including mobile platforms like Android where any newbie can learn how to make his game/animation etc. A lot of work has been made and a lot more is to be done. It might need to hire programmers to make an engine for Android, and Mac OS, then some in-house testers for stability among these platform

    ReBOOM is a direct port of BOOM 2.02 to SDL2 aiming to be as close to the original as possible while adding Quality of Life features to it, such as always on stats. ReBOOM is demo compatible with BOOM 2.02. Please note, that this is essentially BOOM 2.02 compatible, it is NOT compatible with many wads 'claiming' to be Boom-compatible. Many of these modern Boom wads are in-fact only PRBoom-compatible and are not classed as Boom-compatible by myself or by historical Boom. It is pure fantasy. ReBOOM was primarily developed for GNU/Linux systems.
