Hello and Welcome!
It's good to find you planning to teach yourself programming. The good thing about that is, you can stay on one topic for as long as you want until you get the hang of it. And aside from that, you get to schedule when you will be able to do some exercises, or read up on it.
These days, the most common source of information might be the internet, when it comes to computer programming. Of course, this forum is part of it, and there are lots of information here for most well-known programming languages.
If you are interested in making simulations and designing games, well, the programming language I would recommend would be C++. Yeah, that sounds so old-schoolish, but believe it or not, it is still one of the most widely-used languages in simulations. In fact, last semester, I took a course on it, and the computer sim book made by Law and Kelton (forgot the name, but it's the 8th edition) still uses much C. That's different from C++, but still with some of the same concepts. C++ may be somewhat boring in the beginning, but usually this is the case, like Physics, for example, in which the more exciting aspects can be explored once you've grasped the more mundane parts.
Good luck, and enjoy programming!
