There was definitely a bit of "new game with a lot of tags/keywords/rules" to work through tonight, but we had a lot of fun wading in to teh Delian Tomb. It's not as interesting an opening as the Road to Broadhurst (or as varied), but I think the way it slowly unlocks the sheet/actions helped us avoid overloading.
Tons of fun flinging people around, cleaving through minions (the Null: ok, so that's 9 damage against the Sniper. Me: yeah so that kills all of them. Him: no, I just hit the one. Me: No, you overkill all 3. Him, Ohhhhh narrates that).
I think that once people get used to the Tiers of Success and more comfortable with the actions, it can become really cinematic by letting the players narrate how they erode the stamina/move people around/etc based on their rolls.
