Settlers II

Type in Thunder for all buildings. When you typed it a large ! will appear in the right corner of the screen. With thunder on use Alt 1 - 6 for speed control and F7 to view the entire map.
Type in Winter for the Gold version to get the same effect.

There is also an savegame editor that will give you 5000 units of everything in your headquarters.
