Back around 10 years ago, I remember watching an anime (I think it was on CartoonNetwork) in which giant robots fought. The main thing here is that the characters controlled the robots by acting out what they want their robots to do. Their wore black skin tight suits and were in front of many monitors.
If my memory serves correct, I do believe that there was some type of fighting championship taking place. There was a large wasteland where all of the robots and the people controlling them would wander about and look for others to fight.
I am very fuzzy on the details, but I hope that someone can help me with this.
Also, I apologize if I mixed up several animes, or if this has an obvious answer. It has been driving me nuts trying to come up with the answer.
