Yes, editor has great potential possibility. I work just a little slow because I have at the same time :
- to play a little the game to learn
- to read all SC WIE forums threads
- to study in details scripts system
- to study campaigns editor
- to read manuel, in english

(I will probably sometimes ask for things that are already in manuel, because at this time I have not the time to read all)
- to get graphs for these projects (not easy to extract files from old games)
- to prepear these projects
Lot of work but the engine is really powerfull, probably the most detailled editor I have played. I had returned to SC1 some years ago because I did not like the too long AI turns in SC WIE (I play only vs AI*). But now, after some years, the engine AI has been heavy improved in this aspect and turns length is ok.
*except for my "battles" project : when released and completly tested vs AI, I will probably ask for an opponent because in battles, no any AI is soo vicious than a human player
Concerning 1870, I plane in the future to adapt my battle system to battles of this war. When it will be completly released and tested for ancien battles; it wil be easy to adapt it for Seven years war, Independance war, napoleonic war, civil war and 1870 war (and perhaps first fightings of August 1914). The goal is to recreate a kind of "Age of rifles" (the old DOS king game for 18/19th century battles) with the SC engine.
