Most multiplayer games are symetric: all the players have a similar interface and control similar entities. What about making a game where the two opponents control very different entities?
A good way to create such games would be to simply take single player games and give the control of the game world to one of the players. What games could be turned multiplayer this way and how?
An example is Thief I/II. The game master could issue orders to the guards (orders that would be sent either through a speaker system that the player could hear or through messenger guards the player could attack), to the automated guarding systems etc. He would be able to see through the eyes of the mechanical faces. Perhaps even have an in-game character to finish off a cornered thief.
