Linux is nothing. My grandma can use Linux. The only complicated things about Linux are when I choose to make it so, because it’s cool that I can change things. If that’s your draw to Linux, you may be into programming also, and far be it from me to discourage you. But it is exponentially harder to program, a lot of work for games specifically, especially as a single dev, and you are unlikely to make any money from it unless you get good marketing. It’s got to be for the love of the game (literally) and of learning stuff. There’s no way to know if you have what it takes besides trying.
