I live for d12s (especially giant foam ones) so this spoke to me immediately. I like the quick and simple character creation and resolution rules that will make immediate sense to any TTRPG fan, but where this goes fully bananas is in the Adventure Builder. Most of these tables can even be split in half for extra adjectival randomness. Here's one I just rolled:

The party discovers a secret (4) palace (7) located behind a waterfall (6). Inside there is a wild (5) dragon (7) and bored (2) skeletons (12). If you survive the flooding room (8), you might find the priceless (6) cat (4).

This is a ton of info and a quirky adventure born from six tables and ten rolls! Plus, I love the CC-BY-4.0 license, which ensures I will print and bag a handful of copies along with a d12 or two and stash it all around town.
