Uggh, June seems faaaar away... sorry to be pessimistic about it.
There was recently a suggestion on the FreeGamer forums ( http://forum.freegamedev.net/viewtopic.php?f=38&t=2903&p=39050#p39050
) if it wouldn't make sense to try and merge SumWars with OpenDungeons. As far as I can tell, they are build on a pretty similar technical base (Ogre3D and such) but the devil always lies in the details.
Anyways, the beauty would be that those two games actually complement each other nicely, where the OD part could be also used as an ingame level editor and all the monsters and heroes could be used for both types of games.
In addition this would open the possibility for a great new multiplayer type:
"I always wished there was a game with an sort of real-time editor similar to DK (either completely free to build or with game constraints like limited funds or such) where one "Dungeon Master" could play against a hero group that plays like a sort of Diablo like game. Would make for a great combination of COOP gameplay with the old pen and paper dungeon master concept."
Not sure what people think of that over here, but the OD guys seem to be supportive of this idea, however they are facing the same lack of development due to a lack of active coders as SumWars.
However with such a grand proposal it would maybe be possible to attract some skilled coders over at the Ogre3D boards... well at least it would be worth a try
