There are no bounds to the usefulness of this utility. The fact that all bitmaps of buildings are provided allows modders to create infinite permutations of cut and paste building graphics. Personally, I have used them in making bitmap images for the instruction menu of my custom scenarios. Also, modders can use the graphics for beta buildings that are included to add more diversity to the game using AGE2.
The graphics quality is top notch, and lots of eyecandy is also included, making it very complete. Instructions, though they go without saying, really, since there is no limit for uses of this utility, are still included.
This is a must have for any modder or scenario designer. Thanks Devestator!
