We all have a bit of OCD in this hobby. It just isn't always in the same area of the build. Some it's the perfect shade of paint. Some it's painting absolutely every part to include those that aren't seen. Some it's getting absolutely everything perfect and without blemish. Panel lines, and the one for the counters, every rivet accented, Or perhaps following every single step that the powers that be deem necessary to properly build a model. The list can go on and on and we all suffer from at least one of them.
