SimCity 4/Reward Buildings

Reward buildings are buildings which are not available by default, but which need to be earned beforehand. While there are also non-reward buildings which need to be unlocked, no reward buildings are available in the beginning of the game.

The reward buildings can be classified within two groups:

Business Deals
Business Deals will not by default appear in the list. They are only available if you're rapidly losing money and going deep into debt.

Shortly said, it is not recommended to build them. While they do get you some money, they have adverse side effects which can ruin the city, not to mention they reduce the Mayor Rating. On top of that, they cost eons to demolish once you want them gone.

Casino
The Casino can only be built if Legalize Gambling is enacted, otherwise it won't be available. The side effect is that it acts as a huge magnet to crime, on top of the crime increase caused by the Legalize Gambling ordinance. While it does increase commercial desirability around it, the crime mostly negates the effect.

Federal Prison
The Federal Prison should be kept away from residental areas as it has a tremendous effect on residental (as well as commercial) desirability. However, it does act as a larger jail in case you need the capacity.

Missile Range
The Missile Range easily provides the most income of all the business deals. However, there's a chance of a misfire, which can hit your city and destroy several buildings if you're unlucky. This makes it a quite risky business deal to utilize.

Toxic Waste Dump
The Toxic Waste Dump generates huge amounts of pollution, including radiation, which means it cannot be built anywhere near civilization since Sims abhor radiation. It does provide quite some income, though.

Army Base
The Army Base is another producer of radiation (even if not much). However it does have a slight positive effect on commercial desirability and, interestingly, increases the industrial manufacturing demand cap. It may be the most worthwhile out of all the business deals.
