As far as the advisor messages in SimCity 4, apparently you can go into the options menu and turn off "urgent advice tips" to get rid of most of them. If you play on hard, they appear less often. There is also a mod called "shut up advisers" that gets rid of most of them. Or you can press Ctrl + Alt + Shift +X, enter "DollyLlama" (without the quotes) and change their appearance. Type the code in again to change them back.
