Could someone explain to me how in the civ 3 edit i can make it so ptw has no curroption and to make as a scenario, also i wnana make it so i can generate maps like in ptw normally too.

Go to the Difficulty Levels tab and change it there. This will make the game way too easy though. First you won't have corruption to worry about and the choices that come with it, second the AI won't realize that it doesn't either. It won't expand because it'll be afraid of hitting the corruption limits.

lol it makes the game alot more fun from a miltary stand point, and any ways to ai's strat is take cities anywhere no matter how sucky the terrain is, so it won't be a prob.
