We're living in the future!
I just found this demo video of a man controlling his mech just like how they would do it in the movie Real Steel (that's not how exactly the fighting sports in the movie was played, but you get the point).
I heard the news that the World Cyber Games is going to have a mech battle just like this. I think it will be just some small mechs for now. But I can already imagine huge mechs like in Real Steel fighting inside the arena.
