A copy of the game is for sale here in Australia for $75 - way out of my price league unfortunately! But it reminded me that the Java app exists. Having just finished a Magic Realm game PBEM using Robin's RealmSpeak app I thought I'd try again to see if somebody would like a game of Wizards PBEM?
With Realmspeak we played a two month game taking it in turn to move and save the latest game state to dropbox. Next player just loads the last save state using their instance of the application and plays their turn.
