A friend of mine ran this for my home TTRPG group, and it was a blast! If I recall, we used this when our regular game had a plot-dependent PC whose player couldn't make it. This is a wonderful choice for a 1-shot for 4 players, including the GM.
After some initial confusion, the rules helped move the story forward (or sideways, depending on successes...) instead of getting in the way. We spent much more time dealing with our shenanigans than consulting the book. This is great, considering for most of us the first time we looked at the rules was the night we played.
I won't spoil if we succeeded in our mission to get mall pizza, but we recorded our play-through and uploaded it here.
