Okay, so first and foremost, I have the strong belief that you should get your hands on, and read, as many games as possible. So, when you run across something in your favorite game that you don't like, you'll have plenty of options to fix it. Additionally, I'm a GURPS guy. Maths and I are close friends. I like my games like I like my peanut butter--crunchy.

This, however, is crunchy like eggs--and just as inedible. Someone has use the wrong ingredients for this and handled it poorly.

It's much ado about nothing. It introduces all of this extra complexity, all of these extra steps . . . and they do nothing to enhance the game. Saying this is compatible with most D&D publications is misleading--GURPS is compatible with all D&D publications, if the GM is willing to do all of the heavy lifting, which, is basically what this book is--it's a conversion from D&D to . . . whatever this is. This is more like Phoenix Command, but it clearly wasn't written by a genius rocket scientist.

Art should have a purpose, not just be filler. Great googly moogly, this book is so busy with line-art that does nothing for the book. And then there are the pages that it looks like someone just barfed art all over it thinking it would "punch it up" where it really just made it incomprehensible and bloated the file size.

Words have meanings, learn them. Use them. "No player downtime between turns in combat?" How?! Unless you consider the maths you need to keep checking "engagement" you're pretty much all downtime. Don't the other players get to go? Do the monsters? (Spoiler: yes, they still do, and with the massive increase in complexity, there's even more downtime for players.) Using 10 words to say what you could in one doesn't make you look smart, it makes you look pretentious. An introduction to Contract Law would be a good investment--it'll teach you how to write clearly.

If you want a better D&D experience, this ain't it. D&D 5E is a better, player-focused game than this is. This isn't 6E, this is just fractially worse than D&D 5E--and that's coming from a GURPS gamer who thinks D&D 5E is suitable for small children and people recovering from brain surgery.

You would do better with your own house rules--at least you know how they work. There are no examples, let alone worked examples, so there is no way to see how this might work better without taking a massive investment of time to decipher everything and try it out on your own. And, um, yeah, don't do that. This "Player First Design" reads like someone, who doesn't understand how to run TTRPGs, was upset at a GM who wouldn't let them run their Edgy Edgelord of Edgyness character because they don't understand the complexity in setting up a story and running it.

Save your money. Even $0.99 is too much for this. The bulk-padding of random tables doesn't help this book. I haven't found anything in this book that is redemeable. Normally, that would be some art--but, as said above, not even the art is worth it.

And, um, check your file--the page numbers aren't included. But, that seems par for the course.
