Following this project while it was in playtesting was invariably exciting, and its existence has become crucial to my worldbuilding. It's an extraordinarily impressive feat for Rex to have made such a dense, detailed, and engaging set of rules and additions and I hope he can forgive me for occasionally annoying him (/j). Having my name in the special thanks and knowing that I was able to support bringing this project to life fills me with joy. From what I've read during the playtests and since release, I can't wait to pour over this book over and over for years to come.

Sad to see the end of PF1 support from DDS, but honestly one of the best ways it could end. A book jammed full of plenty new abilities for any situation you can think of, excellent customization/flavor options (like creating biotech, arcane machines, or even plant constructs), and even creating new talents via Inventioneering. If you like Spheres content, buy this book, you cannot go wrong with it. I wish the best for the authors of these books

A fine last hurrah for Drop Dead Studios with PF1e! The rules in the book are versatile and allow for a wide breadth of character builds, RP hook for a character or plot, or even just templating for more distinctive magic items. Computation+Transportation makes for the basis for a perfect Construct "Animal Companion" as one highlight. My only real criticism is the vagueness of permanent item pricing. Congrats on this project's completion

This book is amazing. I've never seen so much interaction between interlocking systems in a sourcebook before.

An individual player using this system can be a scrappy tinkerer who cobbles together functional weapons and armor with outlandish properties, or could be a lone tank driver escaping a distant conflict with nothing but his highly customized vehicle that he lives in.

There are gizmos that you can use to build out or modify existing equipment or even structures to incorporate tech into them. Imagine deciding that your castle needs handprint sensors to open/lower the drawbridge, and you've got the idea.

Or you could utilize the content in here to build out the tech in your setting, flavoring it and modifying it to suit factions as you please. There are mechanics and suggestions on how to incorporate all of these to your specific preferences

And just about everything I suggested above can interact with the other systems involved. It's absolutely bonkers, and I'm getting lost in it just like I first did when Drop Dead Studios released the core Spheres of Power, Might, and Guile.

My only caveat is that I am literally using a spreadsheet to build my characters. I count that as a plus, you may count it as a minus.

An amazing tool for players and GMs to include more tech-y themed abilities and characters into their games without the mistakes normally seen in tech-based supplements for games. Highly recommend picking this up.

Using some of the same mechanics and format as Spheres of Might, Ultimate Engineering works to bring 'technology' to your character's fingertips. Don't let the idea of technology in your swords and sorcery game keep you away from this book. Just as Spheres of Might worked regardless of your weapon choices, Ultimate Engineering doesn't necessarily have to involve steam power or harnessing electricity. Examples in the book include technology based on plants and demon forging. Once again the crew at Drop Dead Studios has come up with a way to enable a wide array of character customization in a reasonably balanced format. Also good for DMs looking to have strange and fantastic 'magic items' without going through the crafting rules and risks of balance issues.

A fantastic book to bring high tech to games using Spheres of Might, especially for GMs. Can strongly reccommend it, as well as other books from the same author.
