Continuity

I'm sure not everyone will be fussed on this subject, but to cater for the people who are (mainly myself), I'd like to see all character sheets have a continuity at the top. This is basically what universe they are from. 'Cause, y'know, it'd be weird if you'd been playing a character in Hiro's DnD world, and then suddenly one day he was in my DnD world, since they likely have totally different culture and geography and such. Of course you're welcome to have someone with "Fluid" continuity, or "Undecided" continuity or whatever. But I for one won't let you play a character whose continuity isn't set to the world I created unless I say otherwise.
