Simple idea but whilst ADOM had mountains, it didn't have snow! Levels of snow could be dependent on the time of year, terrain etc. Walking in snow could sap energy (reduced by wearing snow shoes etc.) Skis could give a speed boost and skiing could be a talent. Those without cold resistance or some kind of cloak could be damaged... a bit like the Ice level in ADOM.
maybe some unique terrain too, like corrupted woods that was once a normal pine forest but chaos seeped into it and now it resembles something more along the lines of a very very bad acid trip....only its not a trip!
It was great to see the (*awesome*) JADE video with desert areas, although still no snow as far as I can see... I feel passionate about this as such environments would be easy to implement, open the door to lots of ideas and be lots of fun! I had a few more thoughts about what could be added to our snow environment:
Snow storms: Reduce how far PCs can see.
Quests: Enter a cave of a giant polar bear (for example) either to kill it or retrieve an object. Search for the Yeti to prove its existance. Rescue a NPC stuck on a mountain...
Thanks for the support so far btw! Lets hope we can get the support of the MASTER himself.
Whilst "endagered" species is I think a silly idea for a medieval style of world, there is precedent for certain creatures being illegal to kill because they're the nation's patron animal. A kingdom with a lion on its crest might make it illegal to kill lions for instance. Or it could simply reward those that don't (like with kitties in ADOM). Then again there could be a black market in the city for lion fur if you want to make a quicker profit...
Apart from that, another good excuse for not killing creatures that also fits perfectly in a medieval fantasy world is religion. There could be a religion that forbids e.g. killing felines, because they are considered holy (this happened with cats in Egypt and still happens with cows in India, for example). This could have at least two implications: on the one hand, if your character chose to follow that religion, he would be forced to follow those guidelines or he would anger his god. On the other hand, if your character didn't follow that religion but he went into a kingdom/city that officially did so, he would be forced to follow those guidelines or be arrested. In ancient Egypt, killing a cat was punished with the death penalty!
Apart from that, another good excuse for not killing creatures that also fits perfectly in a medieval fantasy world is religion.
Benefits for not killing or for feeding a holy animal an appropriate type of food ( eg. raw meat to carnivores, plants to herbivores), you have a small, possibly cumulative, chance of recieving a random blessing for a certain amount of time, or a priest of that religion could offer you unique quests. Enemy religions/factions could endorse wholesale slaughter of the critters as well in order to weaken their enemies.
Deserts have already been implemented, so I don't think that cold climate areas with snow are too much of a strectch. I'm against there being a dedicated skill for movement in snow, though--I prefer the idea of having a general skill for movement and/or equipment that can modify the energy cost of movement in inhospitable/exotic environments.
