IC: Marvel Heroic original characters
I'm thinking about a fun setting where you can create your own MHR characters (dice budget/allocation) where you play normal people in our world suddenly transformed into and transported to a superhero world.
You can create whatever four-color, costumed concept you like, it'll just be your character won't understand how you ended up that way. Discovery of what changed you, how you got there isn't a large part of the story, but could be a part of transition scenes and an individual decision.
You don't have to know the Marvel Heroic/Cortex system. I'm happy for this to be a learning game. Character creation would be based on 18 d8 dice allocated to your powers, SFX, and Specialties. Dice can be combined to step them up (2d8=1d10), or cracked to divide them into smaller ones (1d8=2d6).
The premise of the campaign is a Fish Out of Water, with elements of Be Careful of What You Ask For, You Might Just Get It. It'll be a four-color superhero world (think the Justice League or Avengers: EMH cartoons. Those aren't played for laughs, so silly concepts won't work, nor will non-costumed superheroes.
Whether you leap into action, reluctantly do so, or otherwise, you've suddenly got powers and abilities you didn't ask for. You're nowhere you recognize, your friends and family are gone, so that is a sobering adjustment, too. A little pathos with the excitement.
