I think social games do matter, just not nearly to the degree that most people seem to think, judging from how they spend their time. I think the explanation for this is that social games mattered much more in the past than they do now, but most people don't realize this yet. And on the other side, there are a lot more opportunities for technical problem solving, which weren't available in the past.
- Not getting bullied or pushed around by other people
I was bullied in school, but eventually graduated, and I don't think anyone tried to push me around after starting work. If they did, I would have complained to my boss or changed jobs. In a less mobile society, if you didn't know how to "handle yourself", you were probably stuck with low status for life.
- Finding mates outside a narrow nerdy minority of people
Being single isn't that bad. I imagine it was a lot worse in the past, where there was much less you could do to entertain yourself.
- Networking
I spent most of my spare time in college writing an open source C++ library, which led to plenty of business and job opportunities. I really doubt that I would have gotten more opportunities if I had spent most of my time socializing instead. I also didn't put any effort into networking after starting work, and I don't think that it's hurt me much.
- Business and job negotiation
Looking back at my past job interviews, I now realize that when the interviewer asked me what salary range I was expecting, that was supposed to be the start of the negotiation. At the time, I just told them honestly that I don't know, and that I care more about how interesting the job is than the salary.
That was probably not optimal, but I don't think I was hurt too badly by my lack of negotiation skill. And the reason for this is that salaries and other prices are constrained by market competition, and markets are more efficient today than in the past, leaving less room for negotiation.
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
