Babies and Broadswords might sound strange on the surface, but it is a surprisingly well developed game. There is enough content provided that this could be a multi-shot or even a daily-driver type of campaign. It's also simple and easy enough that it can be played in a single game, and character creation takes like 30 minutes from start to finish. The rules are similar enough to other TTRPGS that newbies would pick it up fast, but still unique and varied enough that vetern players would find it just as intriguing.
I own the Book With All the Rules and Crawl of Cuthulu, and they are well worth the low price for the physical copies, let alone a few bucks for the digital versions.
One of the best things about this game is the writing; the jokes are funny, the story is campy and silly, and the sublte nods to pop culture nerdom are on point.
I highly recommend this TTRPG - it is one of my new favorites to play as one-or-two shots, and also a great introductory game to the TTRPG world. Buy it!
