Okay so looking through the Artifacts and Legends book I saw an item called the Scepter of Ages, which besides for being an absurdly awesome weapon as far as flavor... allows someone to use it as a time machine.
Paizo was wise and kind enough to include a chart of the different eras of Golarion with this item and the first thing that came to mind was to run a Chrono Trigger style game where the players were era hopping trying to dispatch a villain with the scepter.
I was wondering if anyone has ever run a game with time travel before and if they had any idea/concerns/advice for someone looking at this as a campaign.
