I love the Paizo Critical Hit and Critical Fumble decks. As such, I have implemented a house rule to use these. All 20s are critical hits and all 1s are critical fumbles. Pull from the deck and follow what it says. If the card doesn’t apply (for example, damages your shield but you aren’t using one), you can exchange the card. Otherwise, let chips fall where they may.
I don’t assign experience. Instead, after several encounters, I just tell everybody to level up. I prefer that the party all stay the same level. This prevents people from out leveling others in the party. There is no set number of encounters, as I tend to determine it much has actually been accomplished.
Please set cellphones to vibrate. Generally, texting and talking on the phone are distracting while playing.
