Could be the world map part of Heroes of Might and Magic, having some kind of pre-determined combat issues like gitc. Combining micro and macro, training units and moving your hero / troops around, maybe like CR a bit. Could be nice to have so counter unit tactics, like unit A does 150% damage to unit B, unit C beats unit A etc, so you train accordingly.
We'll see, I feel both combat part of might and magic or the world map part would be pretty easy to have a "perfect solution", but most games based on real game had a twist making it more CG friendly, I'm not worried. Like Code Royale is pretty different from Clash Royale in the end (or did I miss the reference to another game ?)
