I think Models is well worth the read, probably better to start there... I haven't read the Game but I'm sure it's entertaining and fun, since it did so well from a sales standpoint, not sure about the actual content.
IMO, I think you should go listen to, look at, and read anything you can get your hands on until you find something that really resonates with you, since that's the most important thing. Then once you find that, make sure it's legitimate (there's a LOT of bullshit out there) and then model whatever you find until you get somewhat consistent results... then branch off from that to bring in other things that resonate with you as well.
I came from the Mystery Method camp so I have a lot of bias towards them but I know a lot of people feel it's too inauthentic and there are definitely issues from an authenticity standpoint that that has... also, the focus on value, IMO, isn't as good as the focus on framing is, although both work very well. And those things are really the basis for just about everything else that exists out there, for the most part.
There are some other schools out there, like the NLP schools and the pure seduction stuff but I wouldn't start with any of those things, if I were you.
There's also a lot of stuff out there that purely focuses on inner game but most of the people I know who actually do well who focus purely on inner game were either naturals or guys who got good with another method and then ditched the other method (but kept the habits) to join the Church of Inner Game Only.
At this point, there's so much stuff out there... it's really hard to tell someone where they should start without knowing them better... we can just tell you what we think is really good and what works for us... which will be all over the board, since this is kind of a hodgepodge of people from different schools of dating, pickup, and seduction in here.
You could probably skip all that and just start reading some articles on this site, pick your favorite guy to learn from, and then model what they talk about until you get consistent results. Maybe pick up Chase's One Date and start with that? Chase definitely has a lot of good stuff.
