Don't think in terms of growth so much as an outlet for certain energies when I'm creating (or trying to create) games.
It is that, but because it's something real, as opposed to simulated, it gives more growth also. One of the half scary things going on with games right now is that they are good enough to almost give us a feeling of accomplishment, but it's hollow. If I do a model in Blender, my models keep getting a little better and unique. The same with my games, at least if I could settle down with them a little instead of learning a new language or engine every time.
