Re: Time Limit
It does seem to be rather generous doesn't it. Even if you only want to save a few points then I bet most characters could get away with slapping Time Limit (1 day; -1/4) on all of their persistent powers without worrying. Then we'll end up with a world where the morning ritual will be: wake up, turn on persistent powers, not worry about them for the rest of the day. GMs will then be plotting about how their villains are plotting to attack the heroes on the day they sleep in late, when their powers have switched off and they haven;t had a chance to activate them again, just to justify the value of the limitation.
I can see that it might work better if there was a set time the power turned off, e.g. midnight, but even then the ease of turning the power back on means it's still not very limiting.
