Reddit reviews Theory of Games and Economic Behavior: 60th Anniversary Commemorative Edition (Princeton Classic Editions)

I took a semester of an introductory course of Game Theory. We followed the textbook An Introduction to Game Theory by Osborne. The book is great for a first dive into the subject, has ample examples, easy explanations, and is not too mathematically involved. Don't trust the online ratings; this is a very clear-cut book that covers a lot of material.

We also had Theory of Games and Economic Behavior by Neumann and Morgenstern, the founders of Game Theory, as a reference. It covers the motivations for game theory, explains basic concepts (like utility) which are taken for granted, and also explains economic behavior using Game Theory. It's a 600-page monster.
