...The special resources for the Gotm20 game will not work with any other Civ3 or PTW game outside of Gotm20-Spain. To load and play other standard Civ3v1.29 games that have not been upgraded to be compatible with PTW, you will need to follow a similar procedure to reach down into your "resources storage" folder and get a copy of your original graphics files. You may switch back and forth as often as you like as long as you pay attention to the name of the folder where you select the resource graphics from.
