Ngmoco has announced that they will be shutting down four of their games permanently. While three of these games are not on Android at all, one of them happens to be on Google Play and has been for quite some time and has between 500,000 and 1 million downloads. That means there is a decent amount of people on Android who play We Rule that will soon lose the realms they have created.
While We Rule, along with the other three games, will be permanently shut down on March 31st, 2013, all four titles will be pulled from their respective app stores on February 1st, 2013 and in-game purchases should already be disabled by now according to the official post over on the Ngmoco blog.
As for anyone who has downloaded We Rule and is currently playing it, you'll be able to continuing playing it like normal until March 31st, 2013. All unused in-games purchases will also remain available until We Rule is officially turned off.
