I've been working on a few ideas for Monsters. Specifically, a campaign that features a fast-food restaurant named MacDunnegal's moving into a quiet little town. It just so happens that MacDunnegal's has become such an icon in America that their mascots have taken on a life of their own. Literally. Suddenly, the mascots of MacDunnegal's are attacking the town and its up to our heroes to save the day.
The only way to defeat the monsters is to not pay attention to them!
Unfortunately, simply not paying attention to them won't work because the corporate machine has cast such a powerful sigil that the monsters are there to stay. The restaurant brings much needed work for teens of the town (the PCs?), it's one of the only fast food restaurants in town, and since the town is small and boring, it's also the only decent place to hang out. Coming from a small town, I know what I'm talking about on that front.
