The FlightGear flight simulator project is an open-source, multi-platform, cooperative flight simulator development project. The project is primarily aimed at civilian flight simulation. It should be appropriate for simulating general aviation as well as civilian aircraft.

New 3D sound, colour changes based on weather effects, updraughts and down-draughts over mountainous areas and extinguishable wild fires have been added to enhance the simulation

An area where open-source games have traditionally lacked is with regard to delivering high-end graphics capabilities that can compete with modern day commercial games.

In the second Free Gamer interview - over 2 years since the first with grumbel - serial Free game developer Steven Carlyle-Smith (UK) aka Me_Programmer Games was kind enough to take the time to reply in detail to my questions about his development activities. Steve has created a plethora of Free games over the years.

The Australian Defence Force (ADF) has revealed its latest flight simulator runs on Suse Linux-based clusters of Opteron servers and uses an open source graphics platform.

A good open source platform game that never gets a mention is The Goonies: 20th Anniversary Edition. This game is a remake of the classic NES / Master System version by Konami. The same team is also responsible two rather fun arcade top-down racing games, F1 Spirit and Road Fighter, which are also remakes. I'm not sure what the source license is for these (ack, there goes my Free Software credibility) but you can get the source and the games compile / run on the 3 major platforms (y'know, Lin/Win/Mac).

There are dozens, if not hundreds, of open source games that are already native on GNU/Linux. Unfortunately the commercial gaming market lags behind open source game development when it comes to GNU/Linux. Some people using GNU/Linux want the commercial games too. This article is an attempt to assist a move in the direction of GNU/Linux in the commercial gaming market.

Retired Air Force pilot John Wojnaroski can’t seem to get away from flying and he’s been constructing the “ultimate” flight simulator with authentic screens, switches and even throttle controls. Using scavenged passenger jet parts and the “FlightGear” open source simulator platform, Wojnaroski’s simulator can emulate most jumbo jets and can even perform instrument approaches along with around the world flights.

Wolfenstein: Enemy Territory
A true classic and one of the most played online first-person shooter games, Wolfenstein: ET was supposed to be released as a new mod for Return to Castle Wolfenstein, but the single-player part of the game was abandoned and it was released at no cost, as a standalone multiplayer game.
