Possibility to create larger maps is definitely splendid idea, however as you guys said, creating such maps would be resource consuming. For example I managed yesterday to create some big (I mean really big) maps:
300x300 tiles (unfortunately I forgot to measure the time of generation, but it was somewhere about 10 minutes or less),
350x350 tiles - generation time for this map was 20 minutes,
400x400 tiles - here the time was little longer - 40 minutes, and finally
500x500 tiles - this map generating was really time consuming - 2 hours 10 minutes.
As I noticed about memory usage, it’s not really such big (few hundreds of MBytes).
BTW. I include the generated maps (or rather I should call it saves, because maps are not supported yet), so everyone who would like to see these maps can download them.
