PRTG Catches Network Issues Before They Cause DowntimeReactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Source Engine
Modified source engine (2017) developed by valve and leaked in 2020
The Source Engine repository under that particular GitHub user appears to be a custom (or forked) version of a game engine — likely an engine derived from or inspired by the classic Source engine lineage (or at least the name evokes that lineage). However, publicly-available documentation, community support or clarity about the project’s scope and maturity seems limited: the repo does not clearly advertise a full engine release or wide adoption. As such, it feels more like an experimental or hobby project: potentially a work-in-progress engine or engine-in-progress reimplementation rather than a full production-ready game engine. For a developer, this means you're likely to face missing features, limited tooling, and the need to fill gaps yourself, but also that you have a chance to influence or shape the architecture as you develop. -

Multi Theft Auto: San Andreas
Multi Theft Auto is a game engine
Multi Theft Auto (MTA) is a software project that adds network play functionality to Rockstar North's Grand Theft Auto game series, in which this functionality is not originally found. It is a unique modification that incorporates an extendable network play element into a proprietary commercial single-player PC game. Multi Theft Auto is based on code injection and hooking techniques whereby the game is manipulated without altering any original files supplied with the game. The software functions as a game engine that installs itself as an extension of the original game, adding core functionality such as networking and GUI rendering while exposing the original game's engine functionality through a scripting language. Originally founded back in early 2003 as an experimental piece of C/C++ software, Multi Theft Auto has since grown into an advanced multiplayer platform for gamers and third-party developers. -

Xash3D FWGS Engine
Xash3D FWGS engine
Xash3D FWGS is an open-source fork and extension of the original GoldSrc-based engine (from the classic era of first-person shooters), aimed at providing compatibility with the original engine (e.g. games built on it) while extending and modernizing its capabilities. The engine supports multiple rendering backends (OpenGL, GLES, software fallback), modern platforms (desktop OSes, mobile, etc.), and updated features such as better multiplayer, voice chat, IPv6 support, improved virtual filesystem, and support for modern asset formats. For modders or fans of classic games, Xash3D FWGS offers a way to play or build games using the familiar GoldSrc workflow but with updated portability and features. Legacy mods and maps for supported games can often be used unchanged (or with minimal modifications), preserving the classic experience. At the same time, the engine’s enhancements — modern input support (gamepad, touch), modern OS compatibility, cross-platform builds. -

The engine handles essential visual novel conventions like save and load systems, rollback to previous text, scene transitions, and UI menus, so creators can focus on the story and player experience. Because it’s built on Python and widely supported across platforms, Ren’Py games can run on Windows, macOS, Linux, mobile devices, and even in browsers with HTML5 builds, helping developers reach a broad audience. -

Luanti
Voxel game-creation platform with easy modding and game creation
Luanti, originally known as Minetest, is a free, open-source voxel game engine and platform designed to let players, modders, and developers build and play diverse sandbox-style 3D worlds. Written in C++ for core performance and Lua for scripting, Luanti runs on multiple operating systems (Windows, macOS, Linux, BSD variants and even Android), making it highly accessible and cross-platform. Rather than being a single game, Luanti is meant as an engine and toolkit: individual “games” are actually collections of mods — written in Lua — that define terrain, items, NPCs, mechanics, and rules. This modular design enables rich customization and community-driven content: users can install new games, mods, and texture packs via a built-in content browser that draws from a central repository (ContentDB). Luanti supports both single-player and multiplayer via servers; players can host their own or join publicly listed ones, with server-side mods being applied automatically. -

OpenDiablo2
An open source re-implementation of Diablo 2
This is an open-source re-implementation of the classic action-RPG Diablo II (including its expansion) — or rather, a game engine that can run it. The engine is written in Go and cross-platform, aiming to bring the feel of the original 2000s-era ARPG to modern systems. Because the project does not include the original game assets, users must supply their legally purchased copy of Diablo II / Lord of Destruction; the engine then loads the MPQ archives and runs the game. The project is organized into a core engine (now evolving into a more generic 2D ARPG engine under Abyss Engine) plus toolset and support libraries. While still a work-in-progress, OpenDiablo2 has made strides: the main menu works, character selection and basic UI panels load, and movement in the first act is possible. The goal is eventually to support full gameplay — potentially allowing modders or developers to extend or make new games atop the engine.
