Thank your very much for your answers, JeromeGrasdyke

Although we're still a bit left in the dark considering the tools, I can completely understand that just releasing company made tools isn't always the obvious thing to do. Still I would like to add that mods do sell games. Not all people might be interested in buying a roman game, but if there are fantasy, medieval or napoleonic mods with a large modding community behind it then it's a different story. At the moment we're limited to tweaking the original game and IMO that is waste of the huge potential that the engine has.

Still many thanks
