FYI
Downloaded a game from MyPlayCity several days ago. Was careful to delete the pre-checked add-on items. Bottom of box displayed message that the MyPlayCity Toolbar would be installed in order to play the game. Went ahead with installation and toolbar did install into Firefox. Next time I attempted to open a new tab using the 'tab box', nothing happened. After going into my add-ons and uninstalling the toolbar, the tab box worked correctly. Haven't tried playing the game since removing the toolbar, but am guessing it may still work as I play it offline (DSL modem off).
Thought you might want to check this out and, if you get the same results, pass the information along to the games community.
Thanks for the great job you do moderating the games giveaways.
