I was thinking of a real time strategy rpg, where you play as sort of a mission control. You support character troops as they move on maps to finish objectives. It is your duty to provide them with relevant field information based on their surroundings, and assist in tactics and strategy (suggest splitting up, guard, hold position, give options and multiple routes). Each character has a similiar but different AI that is relevant to their characters. Through the intro and story dialogue you can learn more about the units, their habits. You cannot control characters, but as a guide you are very much central to the game.
There would be multiple modes in the game, including:
Single player campaign
-roguelike
AND/OR
-story based
Skirmish between yourself and another team (AI, or multiplayer)
