I used this adventure for my solo supers game. Enough detail was included to run the game along with game stats etc. The NPC hero included became a recurring feature of my campaign.
I particularly enjoyed the slightly camp-y retro feel to the adventure. Giant bugs straight out of a 50s movie. I wouldn't have thought to include this sort of subject in my ongoing game without this as a prompt and it made an interesting and creative side-trek. I bought all of the volume 1 Improbable Tales separately and they are what I reach for whenever I need something unconnected to the major campaign themes which feels different and fresh.
