Last time we played some Fate, we got in the following scenario:
A burglar PC gets into trouble in some cellar and gets cornered by his nemesis and about 10 of his thugs. His nemesis wants to 'set an example' and capture the PC. Of course, the PC isn't having any of that, and we initiate a chase scene. By crafty use of Fate points, good dice rolls and quick thinking, the PC manages to make a run for the stairwell, leaving the goons and his nemesis behind his eating his dust.
The PC is now on 0 Fate points and is running up the stairs with goons in hot pursuit. Then the GM proposes a compel: "Remember that metal door you went through to enter this cellar? I think the nemesis locked that door and unlocking the door would take too much time to prevent capture—and you won't have enough time to break the door either."
And with that compel, the GM has forced a straight-up fight, with the PC being severely outnumbered. The PC is no combatant at all and decides to concede, with the player remarking being unhappy with the situation and feeling cheated and state that the compel is too harsh.
I'm wondering, is a compel that will result in a concession too much? Having a compel forcing someone to be taken out seems way to punishing for a compel. And conceding falls in that same category?
