Weird Frontiers is strong! It was what introduced me to Dungeon Crawl Classics RPG. WF has the same playfulness and creative juice inducing as DCC, just with a western flavor.
By just looking through the book (a thiccc boy!) you can see it was prepared with blood, sweat, and tears. If you are at all interested in a western theme, Weird Frontiers is one to put on the top of your list!

I've read this and watched a bit of a play through, and I'm really excited! I was just introduced to DCC RPG and I think this is going to fall right in line with the fun of that! My only feedback is that I hope that more examples of the rules are included in the complete book. There were a few paragraphs in this quick start I had to reread carefully just so I could understand how the mechanic works.
