Not necessarily classics, but my top 4:
- Technical Game Bible by Saul Tee.
Imo the best book on game that I have read. Not super thorough, but writing and examples are great. Technical game, but without a lot of the weirdness that most older stuff has.
- Game Solved.
Badly-written and way too long and rambly, but the most advanced piece of content on game that I've ever seen. Really made me rethink a lot of things, and brings a really interesting perspective to game. Really want someone to discuss this one with
- Becoming the Ultimate Man by Ultimate Man Project
Expensive video course, not a book, but I had a lot of influence from UMP when I started cold approach. I'm not as crazy about them now (still good though), but there is still a lot gold there, particularly on sexualizing, pulling, and dealing with objections
- How to Make Girls Chase by Chase Amante
GC got me into game years before I started approaching. The blog as a whole is probably a bigger influence on me than the book, but I probably wouldn't have had my years of wild dating adventures if not for finding this site. Still, I'm not sure why, but the book and writing style has a hard time keeping my attention (and I love Chase's writing style and insights on the GC blog).
Most other classic pua stuff I've tried to read has just felt inferior to these ones. Too much shoehorning psychology (or sometimes sales) into places where it's not necessary, and too much focus on stuff that sounded neat when I was a beginner but feels more useless now. Reads too formal, or too lame/nerd-y (like how someone who doesn't get laid would talk).
Honestly, I feel like there is still so much potential to write a pickup/game book that far exceeds anything that's been written so far
