to be honest, i find this rule quite "useless".

When you say "I can deal with that problem, but it will be expensive, or f××king expensive, allways means: Give me four or five fate point.

Or when you play with Harry, and you say, let me Fuego the living snot out of that guy, everyone knows, they only have to kick him, to have four life left.

So yeah, we can't communicate with exact numbers, but I don't realy think it makes it harder...

But once we made a "silent game" we could talk, but nothing about the game. Now that was hard XD
