Here's a little extract from the Kickstarter description:
In April 2019, Necrotic Gnome Kickstarted Old-School Essentials — a role-playing game of magic, monsters, and adventure. Following the incredible success of that Kickstarter, Exalted Funeral and Necrotic Gnome are joining forces to produce a massively expanded version of the game plus a set of brand new adventure scenarios!
Old-School Essentials Expanded
The base Old-School Essentials game is a faithful retelling of the 1981 Basic/Expert rules, beloved for their simplicity, clarity, and flexibility. Sometimes you want MORE though!
In answer to that call, we're now primed to produce a massively expanded version of the game — Old-School Essentials: Advanced Fantasy — adding reams of exciting content inspired by the ever-popular Advanced 1st Edition rules. All that delicious esoteric 1970s flavour you crave is here — assassins, poisons, drow, half-orcs, mimics, xorns, vorpal swords, ioun stones... even the dreaded tarrasque! More classes, more magic, more monsters, more options. All 100% compatible with the Basic/Expert rules and presented in the familiar Old-School Essentials style.
Just like previous Old-School Essentials products, Old-School Essentials: Advanced Fantasy will be produced at a deluxe level of quality — hardcover books with sewn bindings. These will be beautiful and seriously durable books! The new material will be printed in two different formats — slim, modular books and chunky, compiled tomes. Choose the format you prefer, or take the connoisseur's option and choose both!
