Terrifying, or expected? Last time I went to the mall about Christmas time I went wearing armor and with extra ammo, just sayin'.
Possibly both. I ever have a child.. someone(s) is pulling Overwatch when its my child's turn to go on Santa's Lap.
As for the campaign, there's already a disclaimer on Character Sheets. (* You will be fighting both SC2 and FantasyCraft NPCs. There will be WTF moments. In those moments, rules go to the NPCs. They don't play by our rules, we got stuck playing by theirs'.) The rulesets are close enough to survive a head on collision. And when they don't, it adds to the "This stuff ain't from 'round here!" vibe.
