@kaputtnik: yes, that is snow - my mistake
@all: discussion about adding new maps was about a year ago. I started to provide map packages with best maps (from my point of view). I wasn't testing them by playing, but I was editing them and look for basic resources, place to live and map quality (is a map just flat or it is more interesting?). That was lots of work. I know that this "packages" are a bit out of date now, but it is a good start for other testers
Also there is some info about time when the map was created and if it is "new builds" or build-18 and earlier.
There is small problem too: what about copyrights? I am not sure if all maps are "GNU". Do people want to add their maps to widelands official build?
And my last question: how many maps should be official?
