Raliuven, you forgot earthquakes/tsunamis and hurricanes/typhoons/cyclones, also droughts and excessive monsoon rains. Levees can break and/or have to be blown up, as is presently occuring on the Mississippi and Missouri Rivers in the US. Then there are things like oil spills and major industrial accidents such as the Bhopal disaster in 1984. Quite simply, the more natural disasters you put into a game, the lower the player acceptance is going to be. As those have to be random events, occuring without warning, players are not going to like having their plans mangled by the game mechanism.
Those tunnels in Switzerland that you drove through, Theov, all have pre-placed explosive chambers built in, so that in a time of war, they can be blown shut if need be. That is one of the ways that Switzerland stayed out of WW2.
The game does not include chemical and biological warfare in it, although it does have nuclear weapons. Chemical and biological warfare is something that makes people quite uneasy, because it is so terrifyingly simple to do. Any pharmeceutical firm facility doing research on advanced antibiotics doubles as a biological warfare research facility as well, and represents the possiblity of a major biological accident, see the Sverdlovsk Anthrax outbreak in 1979.
Any chemical firm researching insecticides or herbicides doubles as a chemical agent research facility. The Germans discovered the first nerve agent when doing insecticide research, and some of the current crop of commercially available insecticides that attack insect nervous systems approach the lethality to humans of Tabun. Chlorine and phosgene were two of the most lethal chemical agents in World War One, both are produced, shipped about, and used in quantities of hundred of thousands of TONS, for use in chlorination of water, the production of bleach, and the manufacture of PVC pipe, among other uses. In 1943, a US production rate of 700 tons of Phosgene, or 8400 tons a years, was viewed as fully adequate for projected military usage. Currently, a plant producing 10,000 tons of Phosgene a year is viewed as the minimum commercially viable. Hydrogen cyanide is still a standard chemical agent, and is produced in enormous quantities for industrial use. It has the nasty capability of breaking down your gas mask's charcoal filter, rendering the mask ineffective. The UN treaty barring the research, development, and production of chemical and biological agents is worth considerably LESS that the paper it is written on. Would you like to see that added to the game?
As for illegal drugs, any game where the production, distribution, and use for whatever purpose of illegal drugs is built into the game is Dead On Arrival in the US. Your major retail chains are not going to touch it, nor will any US-based online distributor. Every game company here in the US knows that that is a Kiss of Death for a game design. An independent non-commercial modification of the game can get by, but having that as an integral part of a game is not going to happen. I have already gotten into serious trouble with the moderators for some of my comments regarding mods of the game using illegal drugs, so I will not say any more on the subject.
In summary, Theov, if you want some of your ideas in the game, modify it to suit your preferences. Do not hold your breath waiting to see them as part of a commercially produced game.
