redmarkus is there a manual or wiki for the DCCB editor? On of the reasons I haven't bought it is that I couldn't find any info on the editor. Another reason is that I didn't care much for Advanced Tactics, although I'm not sure that I gave it a fair shake.
There is an Editor manual included with the game and the developer has been posting some 'how-to' guides. I won't claim that the editor is easy to use, but it is probably the most powerful and feature rich editor ever provided for any game of this type.
