Maybe, You know the Situation: You will design a map with roads from left to right, up to down and different borders (mountains, gras, forrest...) and rivers, seas... like at the first "Civilisation" for example. Is there a good place in the web, where I can find such small bitmaps for free use? I have visited reinerstileset.de , but this is not exactly, what I am looking for... CU Roman

Freeciv has a number of tilesets available, but you''ll have to figure out by yourself under what conditions you can reuse them: the game itself is under the GPL, nothing is said about the tilesets.
