I just got myself back to working on the script (had enought of a break now, working on a script for several hours a day at best got a bit too close to work...) so I'll just produce a short list of things I'm changing in the immediate future (release within 24h):
More low-level randomness to terrain hight map. This means that lone hills, islands and lakes will be more common.
Fixing the remainining flood plains issue (a little thing I forgot about, random numbers...)
Same for forest types, even thought its just cosmetic...
Improving starting position system to use a more "final" form of the terrain data instead of the slighly intermediate stuff it currently uses. The practical upshot is that players will be less likely to spawn in the tundra areas.
Script specific flavoured starts have been posponed until further notice, Flavour Mod recommended...
Reducing the amount of tundra a little bit, there is still to much of it (haven't seen 33% for a long long time thought)
Warp will be coming In 1.1, now heading on to get 1.0 final (not just rc1) finished.
