Reddit reviews Invitation to Sociology: A Humanistic Perspective

I've never read Games People Play, and psychology is not my area of expertise. But, to answer your question, that is not it.

You could read a number of different pop-psych books and each will give you a different perspective. The human psyche is extremely complex, and social interaction is even more complex. It can/should never be boiled down to one idea that supposedly explains the majority of human interaction. Be sure not to take books like this too seriously: Most people do not consider themselves to be "playing a game" whenever they are interacting with others.

My education is not in psychology, but if you are looking for further reading I can recommend some of my favorite books from my undergrad sociology education: (IMO any understanding of human interaction must have both a sociological and psychological component)

Invitation to Sociology by Peter L Berger

Sociological Insight by Randall Collins

The Social Construction of Reality by Berger and Luckmann

These were required reading in a 4000-level class, but this particular professor also assigns them to his 1000-level intro-soc class (which is why he doesn't teach intro soc often). They can be dense, but they are very interesting and definitely worth reading if you are at all interested in sociology.

edit: I don't want to hate on a book I have never read too much, so I will say this: Whenever you read a psych/soc book, especially if it is written for a wide audience, remember to take everything you read with a grain of salt. You may find truth, but you may also find a very smart author who is too caught up in his own work to see the limitations of his theories.
