There's another binary version of FreeTrain available, with additional translations, plugings, and fixing a serious bug in the previous release. It still is Windows only although the next step for the project is to make it run on SDL/Mono instead of DirectX/.NET therefore making it cross-platform.
Simutrans development continues, 0.99.12 now available. I wish they'd open source the game. The original reason not to open source it (by original developer Hajo) was to prevent loss of control of the game (which is a daft reason IMHO - if game development is going well, there will be no fork apart from to take the game in a completely different direction). Lately, since Hajo stopped working on Simutrans and gave the choice to lead developer prissi and other contributors, they declined to open source it because they see no additional benefits from changing the current development model. You can't argue with that, as long as they don't stop working on it, but when they do I guess it will be a case of 3rd time lucky asking for the game to be made available as Free Software.
Also on the Tome I saw Pix Bros. A cross between Bubble Bobble, Tumple Pop, and Snow Bros. Almost as interesting as this guy mastering the Mario music on the piano. (Can you spell 'obsession'?) However the Pix Bros game and website seem to be purely in Spanish (I think) which put me off trying it.
With the new .18 update, there was some improvements made to the GUI, I must admit I tried to play it before, but could not get familiar with this game. I like it very much now. Reminds me a bit of Diablo, with the items and magic system, and on the other side of Jagged Alliance with its round based strategy. Five points for it.
A game everyone should give a try if he likes JA-2 or Diablo. Gives you sure some days/weeks of play...
Finally, slightly off topic but related to FLOSS gaming - pictures of a Dell coming with Ubuntu preinstalled, something that will boost the open source gaming scene that is predominantly based on Linux. The open source desktop reality moves ever closer!
