For a long time I had hoped for a system of weather that would affect players directly. Environment is very important to me and I think it would be interesting if certain tiles were created similar to sand. Imagine going into Ice Dungeon and having the temperature affect you. For example, you might stand on snow and your health would drop slowly due to the cold environment. As you proceed deeper into the dungeon, you might discover ice, which causes you to lose health at a faster rate and going deeper, you may find arctic ice, which would require protective gear of some type to survive in these environments. Also, a gust of wind could cause you to lose small amounts of hit points, where you would hear a sound and then begin to lose hit points. Different wind speeds could determine the loss of hit points. In very strong winds or in gusts of wind, dexterity could also be lost. Other types of environmental affects, like frost burn, 3rd degree burns, and so on could be added that would give people even more of a challenge while being affected by different types of environment. An example might be, a flame strike, where the caster is able to begin with a burst of fire damage and then maintain the spell while causing more damage and changing the state of the character, causing more affect, such as the loss of intelligence and dexterity and possibly causing them to lose consciousness. There should always be a danger and I think that's what alot of the cities lack. There are always environmental issues. Some climates are cold, some are warm, some cause hay fever. It's almost as if you go into a guarded area in the city, there is nothing to worry about. This makes the world a bit dull. There should always be an underlying danger. Weather is a great way to add excitement. Imagine standing in Brit and it begins to rain, then it begins to thunder and lightning, occasionally players are zapped with lightning, unless they are inside but then during rain, water elementals could appear and before long you have a small event taking place because of rain. It could stop raining and the sun could come out or it could continually get worse. So, by adding wind and cold affects and the tiles you could literally change the environment and induce spawns in areas that would not normally have those types of spawns. Another example, snow turning into a blizzard with ice fiends, snow elementals, high gusts of wind and after a period of time arctic tiles. And of course more dangerous, fire could rain from the skies causing buildings to catch on fire and become unuseable. It might sound a bit dramatic but I think to be able to stand somewhere and not think about the danger shows a lack of danger.
