Been seeing this game talked about in the news. Seems Hasbro has decided to use Google Maps and OpenMaps and build a monopoly game around it. So you get to buy streets anywhere in the world and build buildings on it and charge rent, just like the real monopoly.
BUT...they tried to launch yesterday and got swamped with visitors to their site. Approximately 1.7 million unique visitors and they say they are sure this number isn't all.
So at the moment, registration is down until they put in bigger servers to handle the load.
Website is functioning slowly somewhat: http://www.monopolycitystreets.com
