Its a game my Mobage, one of the better game makers for iphone and android apps. Obviously takes place in the Dungeons and Dragons world. Pretty cool class unlock thing and seems to be an event constantly running.
The only qualm I've had about the game is that without paying money most of your companions suck unless you get lucky, but thats countered by the fact that other players you meet can sub in as a companion for a mission
and your main hero is generally strong enough to handle most of the mission on his/her own.

If you need a good time killer or a new iphone game thats free and interesting, try it out!

Game: Dungeons and Dragons: Arena of War

It basically just gives you a decent extra power to start playing with and will put me as one of your friends/companions you can sub in for a mission once a day. My person is rather strong so should be of use
