Watching videos is incredibly important. Small indie developers have to be multi-talented to make up for lack of heads. I’m part of a 3 man team and do the level design, basic programming as well as 3D modelling. I taught myself programming through reading books and messing around with open source games code (Doom, Wolfenstein 3D), 3D modelling through dozens of hours of watching Youtube videos/taking online courses and level design through experience with messing around with old games map editors as a kid. You may not require much skills if you’re the dude in the suit sitting in a multi-million dollar mansion that can fund his ideas, but for us small guys, it’s extremely important to constantly improve as many skills as possible to further our knowledge. It may not seem fun at first for many (I enjoy learning) but it’s just something you have to do, if it were easy, everyone would be doing it. I never believed I could ever make 3D models or even make the most basic code until I got stuck into it.
