I've been useing the same explanation of limits since the early eightys..."You decide how limiting a limit is ,if you say your powers don't work when canadian geese fly overhead,and you say that is common...then canadian geese will fly overhead commonly...even if you're on an alien planet,a exobiology lab will be nearby because you took it as a limit.I.e.; limits do limit characters,so when I run a game limits mostly fall into the called for by conception catagory,despite this foci are not all that rare but users make sure they can get by without them!...Cons are a differant story...at cons most lims are just free points...
