Well for those of you who don't know, Mystery was
Neil's initial Guru. I'm combining them here as they
are more or less coming from the same technique or
strategy.

I am including them here (even though I only give them a four-out-of-ten rating) for the following reason. In conjunction with the above two products - "Dating To Relating" and "Double Your Dating" they can have decent value.

Taken on their own, I would not recommend them for the average guy. The techniques that are given here, definitely work, but they only work on a narrow band of what I would label shallow women.

And when you use the techniques on thier own  (without the more sophisticated understanding of women put forth in "Dating To Relating" and "Double Your Dating"), you yourself become rather shallow. And a lot of guys won't be able to (or won't want to)
use the techniques for that reason.  

Now, there is not anything at all wrong with being shallow, as sometimes you just want to get laid. But sometimes you want more than that. You are NOT going to get the MORE part from these techniques (unless you just derive it on your own from the sheer volume of experience.)

Mr. L. Rx  in Dating To Relating, apparently evolved almost the exact same techniques as Mystery on his own and gives them to you in "Dating To Relating" ( And since he is older than Mystery  he was probably the first one using these techniques.)

But Mr. L. Rx. also tells you many more techniques. Mr. L. Rx shows you how to pick up the other 80% of women in clubs and the other 90% of women in life
that these techniques won't work on. He tells you
how to get a "real" relationshiP and how to pick up
"real" (non-shallow) women.

Mystery and Neil Strauss's techniques are very powerful and work, but the end product is you might not like the kind of girls you get as a result of this, and you might not like who you are being as you do this.

Plus a major drawback is that a lot of their techniques are just memorized lines. Even Neil Strauss has admited that "The Game is changing." So many guys have learned his and Mystery's pick up lines and routines that women have heard them before and recognize them and men are getting busted for using them. 

There are even gurus on the internet who took
Mystery's training and were successful at it, but gave
it up and don't practice it anymore. In one of David DeAngelo's Interviews, he interviews David M. who had become an Internet Dating Guru and quite frankly states he did not enjoy doing the Mystery Method even though he graduated and was successful at it.

So if you can more or less learn the exact same techniques plus a lot more from Mr. L. Rx, why then am I also recommending Mystery/Neil Strauss?

The value of these materials is similar to what I said in the Double Your Dating section above. Mystery goes into more details about the method than Mr. L. Rx does. So, if you are really interested in being a
"player" as your life's ambition, there is value in
getting this information in conjunction with Mr. L.
Rx's data.

Mr. L. Rx actually gives you more techniques to be a player with, but Mystery gives you more in-depth information on this one strategy with this one "type"  of woman than Mr. L. Rx does. Mr. L. Rx gives you more tools to create "pick up" strategies with, but Mystery and Neil give you a lot more information that you can create with once you get and understand
Mr. L. Rx's tools.

The value of Neil Strauss's book "The Game" is that it gives you a very interesting sort of historical application of the techniques to think with. Again, this can be very useful.

Neil has also evloved Mystery's techniques on his own and will give you a slighly different but similar perspective on things and has his own website and workshops in addition to his book "The Game."

So, if  you are the kind of guy like me who is very interested in being very skilled at this "meeting women" stuff, then I would say these materials (The Mystery Method and "The Game") are also a MUST for your library in addition to "Dating To Relating" and "Double Your Dating."

However, I would caution you. These materials aren't going to work for a lot of guys. These materials aren't going to create satisfying relationships for a lot of guys (even if they do get you laid). And these material aren't necessarily going to make you feel good about yourself (unless you have perhaps very low self esteem.)

Taken on their own, they are moderately effective as they do work, but only on a certain kind of shallow insecure woman. They are moderately easy to implement (unless you have moral issues with "bullshitting"), but they are not geared for internet dating and are not going to teach you how to  really relate to a woman and keep her as a girlfriend. (Unless she is totally superficial and remains so the rest of her life.)
