Open Football
Open World Soccer
Open Football development has resumed lately. I downloaded from svn and compiled, and whilst it's not a game yet, it looks very nice and the author clearly knows his stuff if you see the planning and structure that is going into e.g. the animation side of things. Still, if you are a soccer fan and want an ace 3D football game then get in touch the project.
Open World Soccer, a Sensible Soccer inspired game and the successor to Yoda Soccer (which required the proprietary Blitz Basic), is also starting to take shape. Whilst not yet playable, it's not far away from a playable demo release according to the developer.
JCRPG has a new "contributionary release" which introduces a very nice UI as well as a few other world features. What has been, up until now, just a framework is now starting to morph into a game.
Not to be outdone by Teewars which has recently exploded onto the 2D deathmatch scene, the OpenLierox team have been hacking away and released 0.57_beta5. Looks like a large changelog from 0.56 so you'll have to look yourself (on the homepage), but better bot AI, lots of new smaller features, POSIX compatability and a large number of bug fixes and gameplay enhancements.
Freeware Wing Commander fan game WC Pioneer has some mouthwatering models. Free Software purists should check out Privateer Universe which is a nicer community and very active at the moment.
