How in heck can one control four characters in real time? Every game I have ever played with a coterie that was AI controlled botched it badly. Perhaps (I forget what it is called, WAGO?) planning your move and all character including the enemy move at the same time, but that has issues too sometimes. I guess the best way is four human controllers who can plan what to do prior to the real time battle but, then you have to get all those people lined up and not everyone has broad band.
