We tried out the chase cards to resolve a situation in our Griffins & Grottos game just recently and they worked well enough. We've been playing a narrative game, sans minis, this time around, but when one of the players picked up the Chase card deck, we wanted to try them out. We had to fudge things a little because it wasn't quite the terrain in play at the time and we weren't using the PF system, but it resolved things rather swiftly and with some interesting results. We'll probably try them again in the future though I can see how a PF game would benefit from having them on hand in a lot of situations.
