The dungeon, which in this particular spin we're calling vortices, is a dead psionic guy's mind. For three characters who got their asses kicked, they did in fact revise and re-set the entire premise of my setup, through a number of roll-requiring actions, some of them judicious and some not-entirely-on-purpose.
I'm kind of irked that they did not manage more than the most basic success on any of those Dungeoneering rolls, however, because I really wanted to show off the map I made, or some of it, or briefly, as a feature of play going forward. I included some snippets of the map in the video insofar as they saw it up-front.
You also get to see some real-time grappling with a rule or two, although I snipped the worst of my um's and page-flips. If I say so for us, we did a nice job of running the fight - my plan is for each session to speed up the routine considerably, as this game's learning curve is steep to the degree of ability I'm seeking for us, but not actually all that tall.
I'll talk more about the context of Quests, encounters, treasure, and skill encounters if you want. This is a very meaningful dungeon, not so much in the sense of a puzzle although the characters may feel that way, more in the sense of something will happen due to them being in there. And they can shape what that might be, depending on how much they manage to understand and, well, to survive.
Attached you'll see my special customized method for getting the best out of D&D 4E encounters. It's not a character sheet reference at all, it's a play reference for managing order and actions - in such a way that you're both playing my guy and running good tactics without disconnecting the two. In this game, you can work with the rolled order of action, the combination of options within a turn, the ability to "hold" certain actions, the rules for extra actions, and most importantly, how others' actions give you qualities and actions. It's exceptionally dynamic when you get a taste of it, and I've set up the sheet so everyone can look across and see what everyone else might do.
