Does anyone know how to check the PTW version? UK or US..

Well, the *version* number is in the lower left-hand corner of the opening screen.

If you want to know if you have the US or UK release, then I can't help you. :(

Again, this user is using the warez version of Civ3. kentwong, please stop making threads asking for help on a warez copy of Civ3.
