Note that GP said ‘get into the industry’ and not ‘take it up as a hobby’.
But I agree, kleiba should give it a go. I don't want to downplay the value of a co-located team with industry experience but these can be overcome.
Also, without having tried at all, I'm doubtful whether I could land a gig. Even though I've worked in and around IT most of my professional live, I don't have any relevant experience. And I doubt that I could work in an entry-level position: I'm old on the one hand (not attractive for employers) and have more bills to pay now than I did in my 20s (not attractive for me).
If you have any games on PC there is a huge community making mods available on the Nexus mods website. That is one way to start, tons of people have ideas to improve existing games and have found an outlet for it there. I would never have finished Silksong without those mods. There are also a ton of mods via Steam, Skyrim has a all sorts of mods from gameplay to visual changing all sorts of behavior and looks.
It also gives you a chance to see how much you like it before you commit. If you don’t enjoy it enough to keep up doing it purely for fun, you might not like it enough to want to do it as a high pressure career choice.
