Groundhog Day

[McGuffin]

I'm playing in a Round Robin GM Group and have been toying with the idea of a Time Loop adventure. I was wondering if anyone else had experiences on the Day That Never Ends (on either side of the GM's screen). Good idea? Bad idea? Common pitfalls? Advice? Suggestions?

The idea I had for what's behind the loop was that a time travelling hero's (probably played as a speedster variant as far as crunch is concerned) love interest gets kidnapped by their archenemy and as the day goes on they race to find their loved one, only to have them die at the final confrontation with the villain. Cue Heroic BSOD and a 'Nooooooo!!!' that rewinds time back to the morning.

Never done it, but what I might suggest would be, like the actual movie, let the PCs skip certain events after a while. Don't make them refight the same group of thugs every morning unless they want to.

Yes, that's definetly something I want to avoid. Maybe have them come across something they can use to tip of the police so they can catch the badguys before they get up to anything. But yeah, running through the same events over and over again is not a reason to run a groundhog day adventure.

I once ran a D&D game where the heroes got stuck in a mystery involving the death of the Queen and the day kept repeating until the mystery of who killed her was solved. Each time the day started over, I made everyone pass their character sheet to the person to their right. i can't remember all the details now, but it was the court wizard and he was trying to alter reality to hide the evidence that the players were uncovering.
