Real time network game play is the holy grail of Windows Phone 7 gaming and surprisingly it was a MMORPG which got there first.
WoWo world is an eastern MMORPG set in a magical universe, and on the desktop is based on Silverlight technology.
This clearly was an advantage in bringing the app to Windows Phone 7 also, which, as can be seen in the video above, allows complete real time interaction with other players.
The desktop version can be seen at wowo.kx1d.com.
Hopefully this app will inspire developers to create more real time apps, possibly with a bit more shooting, on Windows Phone 7 also.
Thanks Dale for the tip.
