No not a story building incentive. I was trying to think of a reason home planets might be used. Right now the only purpose they serve is to make certain a corporation does not get knocked out of the game, but I think it is realistically impossible that a corporation would fail to control even a single planet. It's not coming from nowhere - someone else raised it. I was just reminded of it when looking at the map and thinking "well, were I to build on Orinshi, I'd do this, but that will never happen" since there is absolutely no reason. Thought that was a just a wasted opportunity, mechanically speaking. Story-wise one can always come up with a reason to build anywhere, of course, but having no reason at all to on a given planet we of course see no builds on any home planet and that just strikes me as really odd. Thinking of other strategic games the home location would be the most important, most defended, or somehow really useful. Just raising that I felt that way again when looking at the map.
