I ran this module twice over the holidays and it was perfect for a relaxing holiday game. I was lucky to have both of my groups be rp heavy, so they thoroughly enjoyed the festival games (both games went well over the 2 hour mark). The third part, "We Need a Midwinter Miracle," even brought tears to the eyes of a couple of my players...:)
The first part, "Into the Festival," is basically a lot of reading and setting the tone. There are a couple of places to make some rolls, but overall, I just filled in the characters about the history of the Midwinter Festival. After you get into the actual festival grounds, the fun starts. There's not a lot of information on the games, so it's definitely an exercise in improvisation. I tried to have fun with it and created a fun atmosphere and NPCs. Both of my groups spent the majority of their time on the games. I had them notice the "alley disturbance" about halfway through the games. That part was the only part that was a bit difficult to fit in. Both groups really wanted to help solve the problem, so I had to really explain that they weren't supposed to...just enjoy the festival.
Part 2, "Stuck in the Middle," was a shock to both groups as I placed all 20 tiny coals and Slab on the table. They quickly got down to business. In my first group, they focused on the combat and almost took Slab out before finding out his secret. My second group figured it out much quicker, by repeatedly getting close to the hole and having Slab shove them away.
Part 3, "We Need a Midwinter Miracle," was great fun to rp, for both me and my players. I feel like the information could have been a bit better organized, but overall it was ok. There were great laughs about how Master Yutun died. Also, both groups immediately feel in love with poor, sad Slab, and came up with really creative ways to help him. Smoll also became a beloved NPC. I had characters spending spell slots to try and warm her. :) Success was had and Ouen had a new friend, and protector for the Snowmen.
Note: I bought cheap plastic sheriff's badges and put snowmen stickers on them to present to my players as their snowmen trinkets. They loved it!
Overall, very fun. It's a good excercise in improvisation and creativity. It could probably be organized a bit better and perhaps edited just a bit more, but my players and I thoroughly enjoyed it. Probably not good for a group who just likes to hack and slash.
