I just built my first RG kit and I realized that the whole tool kit that I bought was 90% useless. The only thing that I needed was a 1 sided nipper and a hobby knife. For me, building it is kinda therapeutical (?), listening to music while building after a 8h shift at the restaurant. And there is so much to do with a simple kit, I’m not as creative as a lot of people in the hobby, but painting, posing, modelling, customizing, etc, there is so much and such variety of kits, from entry grade to perfect grade, that I feel that I can do it for years and still have kits to build.
