Watch this clip starting at around 3:00.
Don't get me wrong. I love Wil Wheaton and there are parts of the scenario that I enjoyed. I just don't like the part where Chris tells the players that they'll be rolling Streetwise. Get 2 successes. Good? Done. Now roll Intimidate or Diplomacy. Get 2 successes. Good? Done.
I like the creative part with the Arcana skill. I'd probably do the same, but when is it that the players get to come up with ideas?
How do they want to find poor Aeofel? How did they know that they should go beat up some NPCs if the DM didn't tell them? What about being in character? What about actually asking the NPCs questions? What about dead ends? Wrong questions? Lies and half-truths? What about actually acting out the intimidation?
The whole "rollplaying" part seems like a railroad to me...
Then there's the part about making an Arcana check to figure out how the portal works (cop out!), and don't get me started about 1 hp minions... It took poor Wil five minutes to describe a freaking zombie... Ugh.
