A more advanced form of energy catch, a game people play to practice sensing psychic energy. One person creates an energy ball, usually by cupping his hands together and thinking about making the ball (though there are other tricks for the less experienced). Another one makes a bat and tries to hit the ball when it is thrown to him. If you have a lot of space and group that really knows what they're doing, you can actually set up bases and put other players out there to catch and throw the ball just like in real baseball (no, I haven't actually done this yet).

Other possible advanced games would be energy lacrosse, energy tennis, or whatever other sport your friends enjoy. Since energy balls are often affected by physical objects other than body parts, it is possible to play a game in which only the ball is made of energy, but this requires a better command of the sport itself, since you can't bend the equipment at will.
