Adults are driven by our evolution to be useful to the community. Games are designed to allow humans (particularly kids) to master skills. Adults ideally should have already mastered much of the needed skills. Hence games cease to be interesting the more one gets older (in general -- there are always plenty of exceptions).
In our modern world however, really useful stuff is done by robots or a tiny part of the population. Thus you have to find meaning on your own and that can be quite difficult.
Being around children teaches you a compassion for others and yourself, something your comment points towards a desperate need for.
If you can find some people to do stuff with that you like, it's quite fun. A lot more fun frankly - as a child, you can only do so much. As an adult with a career in IT, you can do a looooot more. Plus you get to have sex, aw ye!
If you're bored, you haven't found the right people and it likely means you have trouble getting along with them to begin with, so work on that.
You can't work on the approaching because that's not the root of the problem.
It's like this - some people form groups based on chit chat and hanging together. It usually involves alcohol and hooking up, that's kinda the point of it all. And what keeps it going is the never-ending gossip surrounding who did what with whom. That's late highshcool, college/uni and a few years afterwards for some folks.
People who are more intellectually inclined tend to not be a part of those groups because they're 'boring' - which's another way of saying you can't relate to them and they can't relate to you. You're not 'connecting'.
Here's the crucial element - smart people relate based on doing things that take skill, average folks relate based on liking same music, same clothes, etc.
Once you're good at something average people want to be good at - they'll put up with your inability to relate to them based on 'boring' things. You'll be this 'Steve Jobs'-like weird-o they'll come to appreciate. In turn, when they like you, you'll get to have sex with them and stuff like that, and YOU will learn that the stuff you couldn't relate to them about, is not so bad after all. It just wasn't intuitive for you. Once you're good at making women (or men if you're a woman) happy, you all of a sudden have this superpower that everybody wants.
So it's this self perpetuating cycle but you gotta get good at something that is going to give you social points, so that you can catch up on what being 'cool' is all about.
Some of those things are being in a good band, dancing, comedy, sports etc. Nobody cares that you know how to install Linux, but if you can get up and sing at Karaoke night and get a standing ovation, all of a sudden you're a little rockstar.
