Amazon I recently spotted Beneath the Sunken Catacombs in my Amazon Recommendations. Its marketing promised a game that wasn't a retroclone, but instead was a fresh take on the original 1970s gaming experience with some modern and innovative touches with regard to classes and magic.
Beneath the Sunken Catacombs is sold at near cost for $10 (C) on Amazon.ca, and is PWYW on DTPRG as a PDF.
It uses a Modlvay B/X D&D base, and at first glance it looks like a pretty standard retroclone, but as I read it I found some little flourish, tweak, or minor redesign on almost every page of the game, most of which I will detail below.
You will see nothing different on the character sheet of the system: It uses the standard six ability scores, ascending AC, levels, AC, 1-axis alignment, and hit points. Like Swords & Wizardry it uses only one saving throw. Characters retire at level 10. The XP system is pretty standard and uses gp-for-xp. It's Encumbrance system is a bulk system similar to that in Castles and Crusades.
Instead of different hit points for the classes, all PCs and monsters use d6s for hit points, and gain hit dice at different rates: Warriors and Dwarves gain hit dice every level, Priests, and Elves at a rate of around 2:3, and sorcerers and halflings gain a mere 1d6 every 2 levels.
There is a lot ot like about Beneath the Sunken Catacombs if you are looking for a light, fas, well-contained TTRPG. I would consider it a solid contender as a TTRPG I might give to a kind looking for a first D&D-syle game. It is very well suited for introducing D&D4e or D&D5e players into the old school style of play. It takes the heart of some of the best ideas from that era and makes them work in a B/X structure very well.
