Well, I've been playing around with this thing for quite a while and after playing a random game on it I feel it's good enough for a first release -
It's a simple 1024x1024 height-map, originally inspired by the Remstal in Southern Germany, although beyond the fact that the height map also features a valley there's really not too many similarities

Thing about pre-generated maps I didn't like too much was that either you have a completely flat or a completely mountainous map, and the OTTD map generator doesn't seem to be all that fond of huge valleys either, so this is a bit of a combination of huge junks of flat land for nice, simple network construction and some rather difficult regions to provide a bit of a challenge
dunno if I'll make an actual scenario for this one; I'm not too much into unpatched OTTD so that'd inevitably cause trouble and that's before going on about GRF choices ... we'll see. I mean, I'll probably create one for myself, but I'm not sure whether it'll be sensibly usable for anyone else, but then again, if it's already made, I might as well post it, so ... who knows. Won't happen any time soon either ways
Lots of flat land in the North:
Also lots of flat in the South, but going along with some mountains:
Suggestion, comments, feedback etc. are of course always welcome
