A new version of Simutrans-Experimental is available today: Simutrans 110.0.1 Experimental 9.6. This version addresses the long-standing issue of network play between computers running different platforms.
There have also been some general bug fixes, and one or two small feature changes, but it does not yet incorporate all of the latest changes from Standard, as the priority was to fix the networking. It is anticipated that these changes will be incorporated into the next version.
Any feedback related with bug reports, information about how well-balanced that the game is, any difference in approach/strategy needed for Simutrans-Experimental as over Simutrans-Standard or any other useful feedback would, as ever, be very much appreciated.
