If your only hobby is the computer OP it's time to get off the computer.
If that's a bit daunting. Use a social app or look online for events in your area. It doesn't need to start with dating, in fact it really shouldn't start with dating because; speaking as the gay freind and therefore the supreme oracle and confidant for all women internationally (official TM) not having a circle of freinds is something they notice, and people you play games with online don't count. It won't put them off entirely if they're into you, but it sounds like the OP was written by someone who is a little bit more introverted and more of a wallflower.
Kinda forgot for a second I'M the OP.
I'll try not to PL too much, but I want to at least respond.
First, you're correct that I'm both of these things.
Second, my hobbies really are mostly working out, playing vidya and reading. The last 2 are introverted hobbies, working out is also because of where I live. There is no gym here. In fact, and thats my main problem, there is NOTHING here. Events? Hah!
Germany in general is super fucking boring, this place is probably in the top 10 of boring. Germans also are pretty closed up socially. I remember talking to a greek friend of mine and he basically said "just talk to them and compliment them bro". Yeah, if I want to be the town weirdo, I could do that. We don't do that here. Maybe in our cities and/or if you're brown, but not here and not me.
Here is what happens with women in my town: They are done with school, leave to "live life", get knocked up, and come back with husband and kids to live the safest life anyone has ever lived. This place is super boring. The last time someone got robbed my first reaction was " fucking finally, something happened".
I'm absolutely able and even very good at holding proper conversations (even if I don't know what I'm talking about), but I do hate small talk with a passion. I also am admittedly kind of a misanthrope, mostly because of my upbringing. This all makes this very difficult. My usual approach to conversation is: Could we both be doing more useful stuff with our time right now? If I feel the answer is yes, I feel like I'm wasting the time of the other person, and I don't like that.
There are other issues, mostly because of past failures on my part, but all in all, right now, I'm just a pretty average normal dude and its mostly my location that fucks me over.
But leaving isn't the option right now. I have responsibilities.
