Nah, it's dedication, not addiction
@Wade
I really wouldn't recommend a template approach to building up your worlds. I usually dedicate my worlds to just one or two things (depending on the mineral/organic/rad values), resource poor planets usually get dedicated to research, small/tiny resource poor planets usually end up as storage depots (you need lots of storage to make proper use of 'retro-series'). All planets of small or better usually get a shipyard, moons get either a shipyard or training facility.
