Ghost/Echo with a flashback mechanic, basically.
My friend George (and friends) were inspired by these two lines:
[under When You Roll Dice] "When you're especially well-prepared for the action at hand, roll an extra die." Okay, it's two lines in the original doc. Anyway.
The hack is this:
Part 1 - bonus dice
Whenever you commit to an action, and are faced with a danger beyond the Standard Danger, you get a poker chip. You may spend these immediately, or hold onto them.
If you spend one poker chip, you may narrate a flashback involving yourself, for the purpose of explaining why you're particularly well-suited to handle whatever thing you're about to do. If you do so, and it's a reasonable argument (GM is encouraged to be generous), you get a bonus die.
If you spend three chips, you may narrate a flashback involving yourself, and the thing you're good at is a permanent thing - you mark it down on your character sheet/card. You get a bonus die whenever that power or talent you possess is relevant to the action.
We briefly quibbled over whether you could spend chips you'd just earned, and decided to allow it.
Part 2 - danger dice
Instead of assigning dice as you wish, you must have at least one red, one green, one blue, and one yellow d6 on hand. The blue die is always your Goal Die; the red is always your Standard Danger; green is GM-authored Danger; yellow is player-authored Danger.
Your bonus dice may be swapped in to replace any other dice, one for one.
Part 3 - helping and sharing
You can give other people bonus dice that you'd have for the action, if you want. Teamwork is encouraged.
You can spend one poker chip to establish a fact about an NPC. -- this bit we played a bit fast and loose, and not very often.
