If you explore my pages there are about 50 routes that can be downloaded. As they are all under or about 5 megS they are available from the forum pages. All that is required is Blender version 2.79b from the archives to run them. All my routes are absolutely free of change.
Moving on to the critical question. Most are set in the age of sail. The 3 steamship routes can be downloaded from this page and I think the steamship page.
As regards what I make in the future the srtm2 data is no longer available for download. I think you need to register. Luckily I have already made all the routes from Solway Firth along the coast to Lands End and Further I think.
From now on I will be adapting all the routes, already made and adapt them to steamship. With steamships they will not be drivable so they will either be static ‘floating’ or on preset routes. They will mainly be basic cargo ships and perhaps others later, set in motion by keyboard 1 to 9 etc. The entire route including textures, ships, terrain etc are up to 5 meg zipped. and each route already made will be adapted and downloadable from this page.
The era perhaps 1850 to 1950 or therabouts, approximate, etc.
