I can't seem to find a mention of this anywhere.  Please direct me if there is.

A compel can only be refused by spending a Fate Point, so if a character has zero FPs, I see few options:

1) The character cannot refuse a compel.  Could be reasoned as the character doesn't have the "disposable free will" to resist the circumstances.  I don't like this. It takes the choice away, which only happens when a character willing takes on a debt to someone/thing.

2) That character cannot be compelled.  Makes it harder to get FPs to the characters that obviously need them, though it does force them to self-compel.

3) Offer compels with a buy out payed with "debt".  You can dodge one, but it'll get you later.  Doing this at all doesn't thrill me, but it's a comprimise.

4) Allow buying out for free in this specific case.  I've leaned towards this, but it might be to soft. 

Also, I find myself hesitating to compel characters with 1 FP too, because it leads to the above situation.

This game system isn't easy on characters, and I've found myself trying to get tons of points to them to spice up the rolling.  That said, we've only played a few games and we're still getting used to working with aspects, especially declerations.

I'd like to hear any thoughts or suggestions, please.
