I found this game Libre-TrainSim (I don't remember where I found it).
It is a train simulator (that the kind simulators who love in Germany...at 2007 more or less I was with a exgirlfriend in Berlin and we visited a Saturn shop...and yes it is true, there were a lot of boxes of simulator games on racks in the shop)...and in a corner Suse Linux boxes.
It is coded on Godot.
And I have translated the game into spanish, maybe in the next release (the 0.9 version) will have spanish translation.
It is a good game, well it is not kind a game that I love it but it easy to play.
