Before you consider purchasing any game from Shrapnel,....especially Word Supremacy....you may want to do some research on how support is handled here.
Please read this forum thread in the World Supremacy section to see exactly how Shrapnel and the developer of World Supremacy deal, or more correctly, lie and then ignore, the customers who bought a game, realized it had some serious problems, and tried to get shrapnel and the games developer developer to fix the game.
