As an unrepentant Fate Core player / GM, I love playing weird characters with lots of flaws to harvest the sweet Fate Points.

My favorite characters will have a ridiculous backstory with lots of grudges, fueds, romances, and allies who show up all the time in play.

My favorite concept yet was a character in a superhero game that has a pinnacle skill of Contacts (and second of Resources), because he is normal human who is owed favors from nearly every superhero in the universe. He’s a wheeler and dealer of tech both medical, alien, arcane, and divine. Superheroes are always reaching out needing something extra, and he takes payments in favors. Any given time there’s a fight he can call in a favor from any superhero I can imagine (while he hides behind a wall or something). Of course if he doesn’t roll well enough, the superhero in question was busy, tied up, unconscious, didn’t have their phone, etc. And then he’s in trouble! Good times.
