- Linux game database - primarily for Linux games that are beyond the planing stage and have released more than tech demos, ether as source code or binary files. The information about a game is usually taken from the game site. The games are carefully categorized and presented with screenshots and videos. The submission guidelines explain what kind of Linux games are in the database. You can browse the database whilst applying a lot of filters to tweak the output. This site uses two methods to rank games: user votes and popularity. Popularity is the sum of visits for the past three days.

- https://en.wikipedia.org/wiki/Maze_War - (also known as The Maze Game, Maze Wars, Mazewar or simply Maze) is a 1973 computer game which originated or disseminated a number of concepts used in thousands of games to follow, and is considered one of the earliest examples of, or progenitor of, a first-person shooter. Uncertainty exists over its exact release date, with some accounts placing it before Spasim, the earliest first-person shooter with a known time of publication. Although the first-person shooter genre did not crystallize for many years, Maze War influenced first-person games in other genres, particularly RPGs. The Maze War style view was first adopted by Moria in 1975, an early RPG on the PLATO network, and further popularized by Ultima and Wizardry, eventually appearing in bitmapped form in games like Dungeon Master, Phantasy Star, Eye of the Beholder and countless others.
- Ars Technica: Want to see gaming’s past and future? Dive into the “educational” world of PLATO - The PLATO system was designed for education. It had a programming language called TUTOR that was simple enough for non-technical people to use for writing software; it also notably offered a social environment. It was an online community as much as it was a computing platform, and in this capacity it envisaged much of the future of communication. PLATO had chat rooms, message boards, touch panels built into the (flat, plasma) screens, emoticons, animations, virtual economies, and more.
For those who wish to try the games described in this article: you can register an account and download a terminal emulator from cyber1.org, which will grant access to notesfiles—which were used as message boards—and thousands of lessons. Some of these are games. If you've never used a PLATO terminal before, you may struggle at first, but there's plenty of help available to support you. I'd recommend you enter the phrase "bigjump" (without quotes) once you get to the Author Mode display, as that gives quick and easy access to everything else and gets you past the initial "huh?" hurdle of using non-GUI computing platforms. But PLATO also had a less heralded but equally influential component. And even if history has glossed over this detail and neglected to celebrate it, PLATO's gaming archives remain unforgettable for anyone who was there to experience the platform. These "lessons" infuriated administrators, delighted students, and, importantly, pushed the system to its limits. 
- cyber1 - the name for our mainframe-based CYBIS system. To those familiar with PLATO, CYBIS, or early NovaNET, cyber1 will feel like coming home again. Cyber1 runs on top of NOS, the CDC mainframe operating system, generously contributed by BT Consulting & Systems Integration Services (formerly Syntegra). NOS in turn runs on top of DtCyber (watch out, this is a link to a .pdf), a software emulation of a CDC Cyber mainframe, created by Tom Hunter.

- MAME - a multi-purpose emulation framework. MAME's purpose is to preserve decades of software history. As electronic technology continues to rush forward, MAME prevents this important "vintage" software from being lost and forgotten. This is achieved by documenting the hardware and how it functions. The source code to MAME serves as this documentation. The fact that the software is usable serves primarily to validate the accuracy of the documentation (how else can you prove that you have recreated the hardware faithfully?). Over time, MAME (originally stood for Multiple Arcade Machine Emulator) absorbed the sister-project MESS (Multi Emulator Super System), so MAME now documents a wide variety of (mostly vintage) computers, video game consoles and calculators, in addition to the arcade video games that were its initial focus.
- Apps/GnomeVideoArcade - GNOME Wiki! - a simple Mame frontend for any freedesktop.org compliant desktop environment. GNOME Video Arcade recognizes that the frontend is not the point; the games are. As such, its chief design goal is to help you quickly find a game to play and then get out of the way. Its purpose is not to help you manage your ROM collection, nor to provide a confusing graphical interface for MAME's plethora of configuration options.
- A Slower Speed of Light - a first-person game prototype in which players navigate a 3D space while picking up orbs that reduce the speed of light in increments. Custom-built, open-source relativistic graphics code allows the speed of light in the game to approach the player’s own maximum walking speed. Visual effects of special relativity gradually become apparent to the player, increasing the challenge of gameplay. These effects, rendered in realtime to vertex accuracy, include the Doppler effect (red- and blue-shifting of visible light, and the shifting of infrared and ultraviolet light into the visible spectrum); the searchlight effect (increased brightness in the direction of travel); time dilation (differences in the perceived passage of time from the player and the outside world); Lorentz transformation (warping of space at near-light speeds); and the runtime effect (the ability to see objects as they were in the past, due to the travel time of light). Players can choose to share their mastery and experience of the game through Twitter. A Slower Speed of Light combines accessible gameplay and a fantasy setting with theoretical and computational physics research to deliver an engaging and pedagogically rich experience.
