So does the game reset to the main menu after an hour - or are you prevented from playing it at ALL after the hour is over? I assume it just restarts you from the begining ...
I remember when the Postal II demo was released with a time limit ... didn't take long for someone to figure out how to set it to an unlimited amount of time. Isn't Lithtech running the risk that someone will figure out how to do that here - which means they'd get the whole game for free?
