Heroic level you have packaged deals. Have handouts that give range of skill level, stat level, and power level and how that compares to your setting. What is a noob? What is competent? Seasoned? Master level?
What is low level, Mid and High in each powerset?
Do you have required limitations and disadvantages?
Suggested advantages? What powers or frameworks are off limits?
Example:I don't like veeps unless severely limited due how past players abused them and slowed the game down.
What concepts do you allow or disallow?
Example : all superpowers were spurred on by the Carrington Event or Haley's Comet. That suggest mutations.
Example : all super powers were based on mystical effects. No power suits or gadgets.
Example: All super powers are based on ESP. No Bricks but you could have powerful Telekinetics.
Hero is tough on a GM because to do it right you have to more world building and do in an easy to digest way for new players.
