Here is a Youtube video of a OpenTTD game. Music is awful, I think. They should have used the music that comes with the orginal TTD.

This is 4 quick screenshots of the different industry types you’ll find in the 4 OpenTTD scenario climates.

Above: Temperate climate.
Below: Artic climate.

Above: Tropic climate.
Below: Toyland climate.

Just making some wild railway tracks and having some fun with it.

This is a OpenTTD heightmap made in MS Paint. I used the mouse to draw with. Better with a penlike device, maybe…? Anyway, this is a great way to makes more complex terrain in scenarios.
