Actaea

If the boundaries of the supernatural are clearly defined, meaning that numerical values are assigned to all available abilities in the game, then things won’t get out of hand. For example, telekinesis can be limited by time and size, and if the GM wants to make the game more “realistic,” it can be made quite weak but still occasionally useful. The same can be done with other abilities, adjusting their power so that they don’t stand out too much, and everything will be fine. Those who enjoy exotic elements will get their exotic elements, while others won’t suffer from the presence of overly powerful characters.
